Q1. A box is sliding up an incline that makes an angle of 27.7 ° regarding the horizontal. The coefficient of kinetic friction between the box and the surface of the incline is 0.113. The initial speed of the box at the bottom of the incline is 2.27 m/s. How far does the box travel along the incline before coming to rest?

Q2. At a construction site, a 15.0 {rm kg} bucket of concrete is connected over a very light frictionless pulley to a 370 {rm N} box on the roof of a building. There is no appreciable friction on the box, because it is on roller bearings. The box starts from rest. Find out the acceleration of the bucket. How fast is the bucket moving after it has fallen 1.3 m (assuming that there box has not hit the edge of the roof?)
