Practice Problem: Box Sliding Down a Ramp

In this video tutorial, a scenario is presented where Lisa asks for help fixing her roof. During the process, a toolbox slides down the roof, and the video explores whether Lisa can catch it in time. The tutorial uses kinematics, Newton's laws, and trigonometry to solve the problem, calculating the forces, acceleration, and time involved. Ultimately, it concludes that Lisa does not make it in time to catch the toolbox.

Explain the process of calculating the net force acting on the toolbox.

What is the total time for the toolbox to fall from the roof to the ground?

What happens when Lisa finally makes it outside?
