Here's a basketball problem: A 83.0 kg basketball player is running in the positive direction at 7.5 m/s. She is met head-on by a 101.6 kg player traveling at 5.3 m/s toward her. If the 101.6 kg player is knocked backwards at 3.4 m/s, what is the resulting velocity of the ...

A block of mass 0.78kg starts from rest at point A and slides down a frictionless hill of height h. At the bottom of the hill it slides across a horizontal piece of track where the coefficient of kinetic friction is 0.29. This section (from points B to C) is 4.08m in length. ...

A skier is pulled up a slope at a constant velocity by a tow bar. The slope is inclined at 22.2° with respect to the horizontal. The force applied to the skier by the tow bar is parallel to the slope. The skier's mass is 56.0 kg, and the coefficient of kinetic friction...
