Mastering Physics Solutions: Sliding in Socks

On January 19, 2014, in Chapter 05: Work and Energy, by Mastering Physics Solutions

Part A = 1.84 m
Part B = 1.55 m

If your speed is 3.00 m/s when you start to slide, what distance will you slide before stopping?
If her mass is 20.0 kg, what distance d does she slide (i.e., how far does she move after the push ends)? Remember that the friction force is acting anytime that she is moving?
