A High Dive A 62.3 kg person jumps from rest off a 3.11 m-high tower straight down into the water. Neglect air resistance during the descent. She comes to rest 1.14 m under the surface of the water. Determine the magnitude of the average force that the water exerts on the diver. This force is nonconservative.

2276.1 N

Explanation:

We are given that

Mass of person,m=62.3  kg

Initial velocity,u=0

Final velocity,v=0

Initial kinetic energy=Final kinetic energy=0

y=3.11 m

d=1.14 m

h=3.11+1.14=4.25 m

Final height, h'=0

Work done=Change in P.E energy

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.

pretty sure it's false
