Mark drags his little brother in a sled as shown in the drawing to the right. In this case, two agents do work: Mark and friction.
Consider each of the following situations separately: (Mass = 40 Kg)
δΈζ F
40.0 kg
A. How much net work (total work done by Mark and friction) must be done to increase the sled's speed from 2.00 m/s to
4.00m/s?
B. Increasing the sled's speed from 4.00 m/s to 6.00 m/s, Mark does +500 J of work. How much work did friction do?
