Question

you and two friends apply force of 400 N to push a piano up a 4.0 m long ramp. How much work in joules has been done when you reach the top of the ramp

Answer 1

Answer: Work = Force x Distance Work = 400 N x 4.0 m Work = 1600 J

Step-by-step explanation:

The work done is equal to the force applied multiplied by the distance moved in the direction of the force. In this case, the force applied is 400 N and the distance moved in the direction of the force is 4.0 m. Therefore, the work done is:

Work = Force x Distance Work = 400 N x 4.0 m Work = 1600 J

So, when you reach the top of the ramp, you have done 1600 J of work.
