I used f=ma to get 99.2N then I used W=fd to get 9920J. This energy is the output, so output/0.25=input. To get a final answer of 3.97 x 10^4 J This is correct?

I used √2gh = v to get velocity (6.3 m/s) then used that in Ek = 1/2 m v^2 to get a final kinetic energy of 690 J. Would this be the correct way to do this?

Oops, that would be 35.7 kg. Then 35.7 x 2.78 to get 99.2 N

Would that be 350 x 2.78 to get 973 N as the force?

Oh ok, sorry about that, I will re-attempt and try to do the problem again with more research. Thanks

Gravity? Not sure

Sorry I am not sure

The kinetic energy would be the force of gravity pulling?

For: a) Avdol did the work because he is the force that is causing the displacement, right? b) Is there another formula we would have to use? I am confused at how this would work out and what the answer would be.
