Problem 9PE

 Problem 9PE

A person slaps her leg with her hand, bringing her hand to rest in 2.50 milliseconds from an initial speed of 4.00 m/s. (a) What is the average force exerted on the leg, taking the effective mass of the hand and forearm to be 1.50 kg? (b) Would the force be any different if the woman clapped her hands together at the same speed and brought them to rest in the same time? Explain why or why not.

Step-by-Step Solution:

Step 1 of 3

We have to find the net force and we have to check the weather time interval is  is same or not when the woman clap hands together under same conditions.

P is the linear momentum

Linear momentum is the product of mass and velocity.
