A child holds a sled on a frictionless, snowcovered hill, inclinded at an angle of 27 degrees.

1) If the sled weights 60 N, find the force exerted on the rope by the child. Answer in units of N.

90 degrees - 27 degrees = 63 degrees

cos 63 = 60/x

x cos 63 = 60

x = 60/cos 63

x = 132.2 N

2) What force is exerted on the sled by the hill? Answer in units of N.

132.2 N tan 27 = 67.35
