DoNow: A rope applies a horizontal force of 180 N to pull a crate a distance of 2 m across the floor. A frictional force of 60 N opposes the motion. What is the net force on the crate. What is the total work done on the crate by the rope? How about friction? (notes)

AIM: I can describe the similarities between a pendulum, spring and roller coaster problem and the conservation laws and equations used to solve them.
