Problem 53PE

on hard surfaces with insufficiently padded shoes produces large forces in the feet and legs. (a) Calculate the magnitude of the force needed to stop the downward motion of a jogger’s leg, if his leg has a mass of 13.0 kg, a speed of 6.00 m/s, and stops in a distance of 1.50 cm. (Be certain to include the weight of the 75.0-kg jogger’s body.) (b) Compare this force with the weight of the jogger.

Step-by-Step Solution:

Step-by-step solution Step 1 of 6 The change in the kinetic energy is equals the work done if net external force on the system is zero. Step 2 of 6 (a) The formula to find the work done is, Also, Therefore, Here is the mass of the leg, is the velocity of the leg, is the distance and is the force. Step 3 of 6 Therefore, the net force require to stop the downward motion is,

Step 4 of 6
