A tornado moving cross a street with a force of 600 N pushes a trailer a distance of 25 m.
How much work was performed in the process?​

Answers

Answer 1

Answer:

W = 15,000 Joule

Explanation:

Mechanical Work

Mechanical work is the amount of energy transferred by a force. It's a scalar quantity, with SI units of joules.

If both the force and displacement are parallel, then we can use the scalar formula:

W=F.s

Where

F =Magnitude of the force

s = magnitude of the displacement

The tornado moved a trailer with a force of F=600 N for a distance of s=25 m. The work done was:

W = 600 N * 25 m

W = 15,000 Joule

which statements describe kinetic and potential energy? check all that apply.

Answers

Answer:

ACDE

Explanation:

Energy is generally described as the ability to do work by a body. There are two main forms of energy which are the kinetic energy and the potential energy.

Other energy forms stems from these two energy types.

Potential energy expressly deals with the position of a body. It is mathematically given as:

             Potential energy  = mass x acceleration due to gravity x height

It is the energy stored based on the position of particles within a medium

These description satisfies options A, C

Kinetic energy is the energy due to the motion of body. It is mathematically given as:

             Kinetic energy  = [tex]\frac{1}{2}[/tex] x mass x velocity²

Also, kinetic energy is directly proportional to the velocity of a body.

The description satisfies DE

Calculate the momentum of a boat with a mass of 95kg moving at 2m/Ss

Answers

Answer:

190 kg m/s

Explanation:

Momentum = Velocity × Mass

→ Substitute in values

2 × 95 = 190 kg m/s

The momentum of the boat of mass 95 Kg moving at 2 m/s will be 190 Kg m/s.

What is Momentum?

Momentum is defined as the product of mass of velocity. Momentum is a vector quantity. Mathematically, we can write momentum as -

p = mv

It is also the measure of the impact force imparted by any moving object, when it comes in contact with some other body.

Given is a boat with a mass of 95 Kg moving at 2 m/s.

Mass [m] = 95 Kg

Velocity [v] = 2m/s

We can write the momentum as -

p = mv

Substituting values, we get -

Momentum [p] = 95 x 2 = 190 Kg m/s

p = 190 Kg m/s

Therefore, the momentum of the boat of mass 95 Kg moving at 2 m/s will be 190 Kg m/s.

A highway speed limit is posted as 90 km/hr. Is this average speed or instantaneous speed? Explain your answer.

Answers

Answer: instantaneous speed.

Explanation: A highway speed limit posted as 90km/hr would be the instantaneous speed because it’s just the speed for that moment.

1. If an object starts at 0 m/s and 0.0001 seconds later the object is travelling at
400 m/s what is the objects acceleration?

Answers

Answer:

4 x 10⁶m/s²

Explanation:

Given parameters:

Initial velocity  = 0m/s

Time  = 0.0001s

Final velocity  = 400m/s

Unknown:

Acceleration of the object  = ?

Solution:

Acceleration is the rate of change of velocity with time;

 Acceleration  = [tex]\frac{Final velocity - Initial velocity }{Time }[/tex]  

 Acceleration  = [tex]\frac{400 - 0}{0.0001}[/tex]   = 4 x 10⁶m/s²

The time for a sound wave to travel between two people is 0.80 s,
The people are 256 m apart
Calculate the speed of sound in air.

Answers

Answer:

Explanation:

Using the below formula

Speed of sound = ( distance between observers) *2/(total time taken)

Now putt the given values ,

time taken = 0.80 sec

distance = 256 m

hence

V of sound= 256*2/0.80

V of sound = 640 m/sec
