A water-skier is being pulled by a tow rope attached to a boat. Asthe driver pushes the throttle forward, the skier accelerates. A69.4-kg water-skier has an initial speed of 6.9 m/s. Later, thespeed increases to 10.5 m/s. Determine the work done by the netexternal force acting on the skier.

A water-skier, moving at a speed of 9.00 m/s, is being pulled by a tow rope that makes an angle of 37.0° with respect to the velocity of the boat (see the drawing). The tow rope is parallel to the water. The skier is moving in the same direction as the boat. If the tension in the tow rope is 125 N, determine the work that it does in 11.5 s.

A 59-kg water skier is being pulled by a nylon tow rope that is attached to a boat. The unstretched length of the rope is 12 m and its cross-sectional area is 2.0x10-5 m2 As the skier moves, a resistive force (due to the water) of magnitude 130 N acts on her; this force is directed opposite to her motion. What is the change in the length of the rope when the skier has an acceleration whose magnitude is 0.85 m/s2

A water skier, moving at a speed of 5.25 m/s, is being pulled by atow rope that makes an angle of 36.8 ° with respect to the velocityof the boat (see the drawing). The tow rope is parallel to thewater. The skier is moving in the same direction as the boat. Ifthe tension in the tow rope is 130 N, determine the work that itdoes in 14.2 s.
