A piece of luggage is being loaded onto an airplane by way of an inclined conveyor belt. The bag, which has a mass of 10.0 kg, travels 4.50 m up the conveyor belt at a constant speed without slipping. If the conveyor belt is inclined at a 30.0° angle, calculate the work done on the bag by: the force of gravity (Wg) the normal force (WN) the friction force (Wf) the conveyor belt (Wconveyor) the net force (Wnet)

The physics of work on an accelerating object. a) A sled is dragged along by a 25.0 N force that is applied at an angle of 50.0 degrees above the horizontal. The sled moves to the right and friction is negligible, so it is constantly accelerated while the force is being applied. How much work is done after the sled has moved 2.5 m? b) Given the motion of the sled, how must the downward force of gravity on the...
