Final answer:
To draw a free-body diagram showing all forces on the crate when the conveyor belt is speeding up, consider the weight of the crate, the normal force exerted by the conveyor belt, and the friction force between the crate and the belt.
Step-by-step explanation:
To draw a free-body diagram showing all the forces on the crate when the conveyor belt is speeding up, we need to consider the forces acting on the crate. The main forces to consider are:
These three forces should be represented as arrows on the free-body diagram, with their directions and magnitudes. The weight of the crate can be calculated using the equation:
Weight = Mass x Acceleration due to gravity
