Problem 25PE

Calculate the force a 70.0-kg high jumper must exert on the ground to produce an upward acceleration 4.00 times the acceleration due to gravity. Explicitly show how you follow the steps in the Problem-Solving Strategy for Newton’s laws of motion.

Solution

Step 1 of 4

A high jumper of mass jump upward with an upward acceleration four times the acceleration due to gravity we need to find the force exerted by the jumper on the ground.

The upward acceleration
