Suppose that you, with a mass of 48kg, is standing on frictionless roller skates when someone throws you a 2.50kg mass with a velocity of 15m/s and you catch it. What will be your resultant velocity?

Answers

Answer:

v = 0.74 m / s

Explanation:

We can solve this exercise using the conservation of the moment

initial instant. Before the crash

       p₀ = m v

where m is 2.50 kg and its velocity v₀ = 15 m / s

final moment. After catching the dough

      [tex]p_{f}[/tex] = (m + M) v

As the system is made up of the mass and the person, all the forces during the impact are internal, therefore the moment is conserved

       p₀ = p_{f}

       m v₀ = (m + M) v

       v = m / (m + M)   v₀

we calculate

     v = 2.5 / (2.5 + 48) 15

     v = 0.74 m / s

An ant starts at −5 m and moves 10 m left, 25 m right, 30 m left, and 5 m right. If the positive x-axis is to the right, what are the final position and total displacement of the ant?

A. position: −15 m; displacement: 70 m
B. position: 5 m; displacement: 10 m
C. position: 5 m; displacement: −70 m
D. position: −15 m; displacement: −10 m

Answers

Answer: D.

position: −15 m; displacement: −10 m

Explanation:

Displacement is the distance travelled in a specific direction.

Given that an ant starts at −5 m and moves 10 m left, 25 m right, 30 m left, and 5 m right

Total displacement = -10 + 25 - 30 + 5

Total displacement = -10

And the position = -10 -5 = -15

The correct answer is therefore D.

position: −15 m; displacement: −10 m

A book with a mass of 1.2 kg sits on a bookshelf. If it has gravitational potential energy of 50 j, how high is the shelf ? The acceleration of gravity is 9.8 m/s 2

Answers

Answer:

B

Explanation:

The shelf will be b) 4.3 m high

What is Gravitational potential energy ?

Gravitational potential energy is the energy possessed or acquired by an object due to a change in its position when it is present in a gravitational field.

given

mass = 1.2 kg

gravitation potential energy = 50J

h = ?

acceleration of gravity is 9.8 m/s 2

gravitation potential energy  = m*g*h

50 J = 1.2 kg * 9.8 m/s^2  * h

h= 4.251 m

h ≈ 4.3 m

There is no friction between the card and the cup.


Inertia will keep the top cup from moving very far. Gravity will pull one cup on top of another.


The opening of the cup is so much bigger than the bottom, even though the cup moves they will both be stacked together.

if 34.7 g of O2 reacts with iron to form 79.34 g of iron oxide, how much iron was used in the reaction?

A.
19.84 g

B.
44.64 g

C.
104.1 g

D.
114.04 g

Answers

Answer: B. 44.64 g

Explanation:

According to the law of conservation of mass, mass can neither be created nor be destroyed. Thus the mass of products has to be equal to the mass of reactants. The number of atoms of each element has to be same on reactant and product side. Thus chemical equations are balanced.

Mass of reactants = mass of iron + mass of oxygen = mass of iron + 34.7 g

Mass of product = mass of iron oxide = 79.34 g

As Mass of reactants = Mass of product

mass of iron + 34.7 g = 79.34 g

mass of iron = 44.64 g

Thus 44.64 g of iron was used in the reaction

In a series circuit, electrons only flow along one path. Given this information, which of the following is an advantage of series circuits?
A.

B.
Less resistance is produced as more devices are added to the circuit.
C.
Series circuits are simpler than parallel circuits.
D.
If one part of the circuit breaks, the other parts will still be able to operate.

Answers

Answer:

C.  Series circuits are simpler than parallel circuits.

Explanation:

In series circuit, all the components are connected in single path of current flow. If one part of the circuit breaks, the whole thing would break and none of the other parts would work. The voltage is not the same everywhere. It is different across each component. In series circuit, net resistance is more as resistance of all the components connected in series are added up. So, the only advantage of a series circuit is that is simpler than the parallel circuits.

Answer:

Explanation:

notice that is you multiply the time with the speed the units cancel to get distance.

therefore

distance=velocity(time)

distance=(3)15

distance =45 meters

7.

Answer:

1. the speed is constant

2. the average speed is .5 m/s

Explanation:

I have attached a graph of the data in excel.

from excel i got the equation of the line to be y=.5x with y being distance and x being time.

the function is a position function so if you take the derivative of it you get the velocity which is .5.

since the derivative is a constant the the speed does not change and the average velocity is the derivative.
