A crate of Mass 50 kg is pulled up a rough incline, inclined at an angle of 60° to the horizontal. Determine the total work done in moving the crate to the top of the incline 20 m high.

Let's solve this problem step-by-step.

The problem asks for the total work done in moving the crate up a rough incline. This usually refers to the work done by the applied force that moves the crate, overcoming both gravity and friction.

Here's the information given:

• Mass of the crate (m) = 50 kg
• Angle of incline (θ) = 60°
• Height of the incline (h) = 20 m
• Acceleration due to gravity (g) = 9.8 m/s²

To calculate the total work done by the applied force, we need to consider the work done against gravity and the work done against friction.
