A 5.0kg concrete block accelerates down a 34 degree slope at 4.2 m/s^2. Find the Coefficient of friction between the block and the slope.
Answer:
The coefficient of friction between the block and the slope is 0.16.
Explanation:
We can find the coefficient of friction between the block and the slope by using Newton's second law:
[tex] \Sigma F = ma [/tex]
[tex]P_{x} -\mu N = ma[/tex]
[tex] mgsin(\theta) - \mu mgcos(\theta) = ma [/tex] (1)
Where:
m: is the mass of the block = 5.0 kg
a: is the acceleration = 4.2 m/s²
θ: is the angle = 34°
μ: is the coefficient of friction =?
g: is the gravity = 9.81 m/s²
By entering the above values into equation (1) we have:
[tex] gsin(\theta) - \mu gcos(\theta) = a [/tex]
[tex] \mu = \frac{gsin(\theta) - a}{gcos(\theta)} = \frac{9.81 m/s^{2}*sin(34) - 4.2 m/s^{2}}{9.81 m/s^{2}*cos(34)} = 0.16 [/tex]
Therefore, the coefficient of friction between the block and the slope is 0.16.

On the moon, the gravity is 1/6 that of Earth. While on the moon, Buzz Aldrin carried on his back a support system that would weigh over 1760 N on Earth. a) What did the backpack weigh on the moon? b) What was its mass on the moon? please show the work
Answer:
a) 293.[tex]\bar 3[/tex] N
b) Approximately 179.41 kg
Explanation:
The given parameters are;
The gravity (gravitational acceleration) on the moon = 1/6 × The gravity on Earth
The weight of the support system Buzz Aldrin carries = 1760 N
a) Given that the weight of the support system on Earth = Mass of the support system, m × Gravity, g (Acceleration due to gravity) = m·g
The weight of the support system on Earth = m·g
We have;
The gravity on the moon = 1/6 × g
∴ The weight of the support system on the moon = Mass of the support system, m × 1/6 × g = m·g/6
∴ The weight on the of the support system on the moon = m·g/6 = 1/6 × m·g = 1/6 × m·g = 1/6 × The weight of the support system on Earth
The weight on the of the support system on the moon = 1/6 × 1760 N = 880/3 N = 293.[tex]\bar 3[/tex] N
b) The mass, m, of the support system on the moon = The mass, m, of the support system on Earth
The mass, m, of the support system on Earth = Weight of the support system/(Gravity(acceleration due to gravity))
∴ The mass, m, of the support system on Earth = 1760/9.81 ≈ 179.41 kg
∴ The mass, m, of the support system on the moon ≈ 179.41 kg.

Answer:
Right direction (i.e towards B).
Explanation:
From the question given above, we can see that the car is accelerating in the left direction (i.e towards D).
Friction is the force that tends to oppose the motion of an object. Since the car is moving in the left direction (i.e towards D) then, the frictional force acting on the wheel will be in the opposite direction i.e right direction (i.e towards B).

A skydiver jumps from a plane and falls for 5 seconds before reaching his terminal velocity. During this 5 seconds interval, describe his acceleration before reaching terminal velocity?
Answer:
His acceleration during the first five seconds before reaching terminal velocity = (W - D)/m
Explanation:
The terminal velocity is the maximum steady velocity attained by a body falling freely with increasing velocity from rest in a fluid, such as air or water
The net force, F acting on the body falling through the fluid is given as follows;
F = Weight force, W, from gravity - Drag force, D, from the fluid
F = W - D
Given that F = Mass, m × Acceleration, a, we have;
F = m × a
The acceleration, a = F/m = (W - D)/m
His acceleration during the first five seconds before reaching terminal velocity = (W - D)/m.

Explanation:
A player kicks a football from ground level with a velocity of
magnitude 27.0 m/s at an angle of 30° above the horizontal.
What is the horizontal distance the ball travels?
(hint: d= 1/2 at^2)
Answer:
37.33m
Explanation:
To calculate the distance using d= 1/2 at², the time taken for this projectile object (ball) must be calculated.
Time of a projectile = 2u sinθ/ g
Where u = velocity = 27m/s
g = 9.8m/s²
θ = 30°
T = 2usinθ/ g
T = 2 × 27 × sin 30°/9.8
T = 54sin30°/9.8
T = 27/9.8
T = 2.755
T = 2.76s
If the time taken for the ball to move is 2.76s, the distance travelled is:
D = 1/2at²
D = 1/2 × 9.8 × 2.76²
D = 1/2 × 9.8 × 7.6176
D = 74.65248/2
D = 37.33m
The horizontal distance the ball travels is 37.33m
The horizontal distance travel by ball is 37.32 meters.
First we have to calculate time of projectile,
[tex]Time=\frac{2usin\theta}{g}[/tex]
Where g is acceleration due to gravity and u is velocity.
Given that, [tex]u=27m/s, \theta=30[/tex]
Substitute values in above relation.
[tex]Time=\frac{2*27*sin30}{9.8}=\frac{2*27*0.5}{9.8}=2.76s[/tex]
The horizontal distance is given by,
[tex]d=\frac{1}{2}gt^{2}\\ \\ d=\frac{1}{2}*9.8*(2.76)^{2} \\\\d=37.32m[/tex]

A cup is sliding down an inclined surface that is not smooth. What is the correct free body diagram for the body?
Answer:
Let's see the forces in the cup:
The gravitational force will act in the plane parallel to the inclined surface.
Because the surface is not smooth, we will have a friction force, which direction is opposite to the velocity vector.
The component of the gravitational force perpendicular to the surface is canceled with the normal force, so we will not have that in our diagram.
The correct option is not shown, so i will draw a simple sketch so you can identify the correct option:
Where the direction of the velocity is shown so we can know the direction of the friction force,
And we assume that both forces are applied on the center of mass, this is an oversimplified case, but this is the approach we usually take in this type of problems.

Write an equation of the line in slope-intercept form.
Please explain.
Answer:
y = [tex]-\frac{1}{4}[/tex]x + 3
Explanation:
The equation of a straight line is given as:
y = mx + c
y and x are the coordinates
m is the slope
c is the y -intercept
The y-intercept = 3;
Slope = [tex]\frac{y_{2} - y_{1} }{x_{2} - x_{1} }[/tex]
x₁ = 0
x₂ = 4
y₁ = 3
y₂ = 2
Slope = [tex]\frac{2-3}{4 -0 }[/tex] = [tex]-\frac{1}{4}[/tex]
y = mx + c
y = [tex]-\frac{1}{4}[/tex]x + 3

You try to hit an annoying pigeon by throwing a ball straight up into the air with a velocity of 16 m/s. What is its velocity 0.5s into flight?
Answer:
20.9 m/s
Explanation:
Given that,
Initial velocity, u = 16 m/s
We need to find its velocity 0.5 s into flight when a ball straight up into the air. Let it is v. It will move under the action of gravity. Using first equation of motion to find it as follows :
v=u+at
Here, a = g
v = 16 + 9.8(0.5)
v = 20.9 m/s
So, the final velocity is 20.9 m/s.

Two students are discussing gravity. One student says that there is a gravitational attraction between the two
of them. The other student thinks this cannot be true, because he cannot feel any gravitational attraction to
the other student. Which student is correct, and why?
The student says that there is a gravitational attraction between the two of them. This student is correct.
What is gravitational force?The force of attraction between any two bodies is directly proportional to the product of their masses and is inversely proportional to the square of the distance between them, according to Newton's universal law of gravitation.
The gravitational force is weak unless there are massive masses involved. As compared to Earth, humans have relatively low masses, which results in a very small and negligible gravitational force. As a result, although it is tiny and imperceptible, gravitational force exists between two people seated near to one another.
Hence, the student, who says that there is a gravitational attraction between the two of them, is correct.
