Solve b and c
Transcribed Image Text:1. A person is standing on a building with a height h. His mass is m and acceleration due to
gravity is g.
(a)
Draw a free body diagram of the person and indicate all the forces on him.
(b)
Find the magnitude of the velocity of the person after he jumps from the
building reaching a height x above the ground.
(c)
We all know from our day-to-day life experience that when someone jumps
from a height and lands on their feet, the jumper always bends the knee a bit. Compute the
force felt by the jumper when he comes to rest on the ground. Also, can you comment on
what happens if someone does not bend their knees when jumping from high altitude? Show
a mathematical reasoning behind your comment.
