A piece of luggage is being loaded onto an airplane by way of an inclined conveyor belt. The bag, which has a mass of 20.0 kg, travels 6.50 m up the conveyor belt at a constant speed without slipping. If the conveyor belt is inclined at a 60.0° angle, calculate the work done on the bag by: The force of gravity (g), the normal force (N), the friction force (f), the conveyor belt, and the net force.
