Chapter 7: Q. 4 (page 176)

How do basketball players jump straight up into the air? Your explanation should include an interaction diagram and a free-body diagram.

Short Answer

Expert verified

The upward normal force owing to the floor, the downward normal force due to gravity, and the downward normal force due to the ball.

Step by step solution

01

Free body diagram

02

Explanation

The player pushes down on the floor.

which in turn pushes him back up.

Because the force of his push is higher than the force of gravity.

The player accelerates upward.
