A young woman on a skateboard is pulled by a rope attached to a bicycle. The velocity of the skateboarder is v = (4.6 m/s)x and the force exerted on her by the rope is F = (17 N)x + (12 N)y.
a) Obtain the work done on the skateboarder by the rope in 30 s?
b) Assuming the velocity of the bike is the same as that of the skateboarder, obtain the work the rope does on the bicycle in 30 s?
