A small boat is crossing a lake on a windy day. During some interval of time, the boat undergoes the following displacement. ∆r = (3.13 m)+(2.81 mj During the same interval of time, the wind exerts the following constant force on the boat. F = (271 Ni-(129 Nj What is the total work done on the boat by the wind over this period of time? Number 485.74 J What is the angle between the direction of the wind force and the direction of the boat's motion during this time interval?
