Question

You push a file cabinet up a frictionless ramp tilted at 10°with horizontal. The file cabinet has a mass of 100 kg and you are pushing with a 700 N force in the direction up along the ramp. The file cabinet has initial speed of 2.0 m/s. It’s moved 8.0 m up along the ramp. Match the answers with questions.

the initial kinetic energy of the cabinet (Ki)

The image depicts a person pushing a filing cabinet up an inclined ramp. The ramp is shown at an angle of 10.0 degrees to the horizontal ground. 

Key elements of the diagram:

- The person is positioned behind the filing cabinet, using force to push it upward along the ramp.
- The incline of the ramp is marked with a protractor-like angle indicator showing 10.0 degrees, emphasizing the tilt with respect to the ground.

This setup is commonly used in physics to demonstrate concepts such as forces on an incline, friction, and the effects of gravity on motion.
