Question

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)

Answer 1

Here

Normal Force = mg cos 30

Friction Force = mg sin 30

Displacement is in direction of belt i.e 30 degrees from horizontal

1. Work Done by Force of Gravity

2. Work Done by Normal Force

3. Work Done by Friction Force

4. Work Done by Net Force

(Because It moves with a constant speed)
