Problem 52PE

large forces are produced in joints when a person jumps from some height to the ground. (a) Calculate the magnitude of the force produced if an 80.0-kg person jumps from a 0.600–m-high ledge and lands stiffly, compressing joint material 1.50 cm as a result. (Be certain to include the weight of the person.) (b) In practice the knees bend almost involuntarily to help extend the distance over which you stop. Calculate the magnitude of the force produced if the stopping distance is 0.300 m. (c) Compare both forces with the weight of the person.

Step-by-Step Solution:

Step-by-step solution Step 1 of 7 The formula to find the gravitational potential energy is, Here is the mass, is the acceleration due to gravity and is the height. Step 2 of 7 (a) The formula to find the net force is, Step 3 of 7 Substitute for , for and for . Therefore, the force produced is . Step 4 of 7 (b) The equation to find the force is, Substitute for , for and for .
