Serway & Jewett β Linear Momentum and Collisions: Problem 31
A 60.0-kg person bends his knees and then jumps straight up. After his feet leave the floor, his motion is unaffected by air resistance and his center of mass rises by a maximum of 15.0 cm. Model the floor as completely solid and motionless. (a) Does the floor impart impulse to the person? (b) Does the floor do work on the person? (c) With what momentum does the person leave the floor? (d) Does it make sense to say that this momentum came from the floor? Explain. (e) With what kinetic energy does the person leave the floor? (f) Does it make sense to say that this energy came from the floor? Explain.
π Solution Approach
Given: 15.0 cm
Find: (a) Does the floor impart impulse to the person?; (b) Does the floor do work on the person?; (c) With what momentum does the person leave the floor?
