A child pulls a wagon with a force of 100N on a rope that makes a sixty degree angle with a horizontal floor. He pulls the wagon a distance of 25 meters along the floor. A: how much force is done in the direction that the wagon moves? B: How much work does the child do?
W = FD
W = FDCosθ
A: W = FD
= (100)(25)
= 2500 Joules done in the direction that the wagon moves
B: W = FDCosθ
= (100)(25)Cos60
= 1250 Joules
Did I setup and solve these problems correctly?
