Chapter 04, Problem 075 Review Conceptual Example 16 as background for this problem. The water skier there has a mass of 65.0 kg. Find the magnitude of the net force acting on the skier when (a) she is accelerated from rest to a speed of 15.0 m/s in 7.00 s and (b) she lets go of the tow rope and glides to a halt in 22.0 s. (a) Number Units | (b) Number Units

A bucket filed wlth dirt of mass 18 kg Is suspended by a rope that hangs over a pulley of mass 31 kg and radlus 0.10 m (figure below). Everything is initially at rest, but someone is careless and lets go of the pulley and the bucket then begins to move downward. What is the speed of the bucket when it has fallen a distance of 1.5 m? m/s

A bucket of water of mass 14.4 kg is suspended by a rope wrapped around a windlass, that is a solid cylinder with diameter 0.350 m with mass 13.0 kg . The cylinder pivots on a frictionless axle through its center. The bucket is released from rest at the top of a well and falls a distance 10.0 m to the water. You can ignore the weight of the rope. Take the free fall acceleration to be g = 9.80...
