1) A passenger at an airport pulls a rolling suitcase by its handle. If the force used is 10M and the handle makes an angle of 25° to the horizontal, what is the work done pulling force after the passenger walks 200m? 2. A 3.0 kg block slides down a frictionless plane incline 20° to the horizontal. If the length of the plane's surface is 1.50m, how much work is done, and by what force? 3. A boy pulls a 20kg box with a SON force 37" above a horizontal surface. The coefficient of kinetic friction between the box and the horizontal surface is 0.15 and the box is pulled over a distance of 25m. 3) what is the work done by the boy? b) what is the work done by the frictionless force?
