Assuming the pilot's mass was 95.0 kg and his terminal velocity was 40.0 m/s , estimate the work done by the snow in bringing him to rest. Model him as a particle.

7.6*10^4J

Explanation:

Given that m=95kg

Final velocity= 40m/s

Using W=0.5 m (square of (final velocity) - square of (initial velocity))

= 0.5 * 95 * Squared of (40)

= 7.6*10^4J

the box does not move because you need to use a force greater than 300 n. you are only using 50 n. it needs to at least be 301 n for the box to move because then it is an unbalanced force and it will move the way that the greater force is pushing it. if you use only 300 n it will be a balanced force and will not move because the force you are exerting on the   box is the same as its force.

hope this !

im sorry if i went too in depth, i am going to include a link to a video on khan academy that will explain this.   hope that you like the video and that it explains more in detail to you.

that is the link.
