Problem 69PE

Concepts A 105-kg basketball player crouches down 0.400 m while waiting to jump. After exerting a force on the floor through this 0.400 m, his feet leave the floor and his center of gravity rises 0.950 m above its normal standing erect position. (a) Using energy considerations, calculate his velocity when he leaves the floor. (b) What average force did he exert on the floor? (Do not neglect the force to support his weight as well as that to accelerate him.) (c) What was his power output during the acceleration phase?

Step-by-Step Solution:

Step-by-step solution Step 1 o f 12 The work done by a force over a displacement is given by the expression: Here F is the force, d is the displacement and the angle between them is . The rate at which work is done will give the power. It is expressed as: Here t is the time for which work was done.
