A small boat is crossing a lake on a windy day. During some interval of time, the boat undergoes the given displacement A. Ar= (3.15 m) 1+ (2.75 m)j^ During the same interval of time, the wind exerts the given constant force F on the boat. F= (255 N)1 (111 N)J^ What is the total work W done on the boat by the wind over this period of time? W = What is the angle between the direction of the wind force and the direction of the boat's motion during this 0 = time interval?
