Question 1:
A horizontal towrope exerts a force of 200 N due west on a water skier while the skier moves due west a distance of 50 m.
(a) How much work does the towrope do on the skier?
(b) How much kinetic energy is transferred?
(c) If the water skier + skies weigh 650 N, what is the final velocity of the water skier after 50 m if she started from rest?
