Q1. A sled is being held at rest on a slope that makes the angle with the horizontal. After the sled is released, it slides a distance down the slope and then covers the distance along the horizontal terrain before stopping. Find the coefficient of kinetic friction between sled and ground; assume that it is constant throughout the trip.

Q2. How much work did the movers do (horizontally) pushing a 150- crate 10.2 across a rough floor without acceleration, if an effective coefficient of friction was 0.50?
