Question

1) A box that has a mass of 10kg is on an incline plane that has an angle of 30degree with respect to the horizontal. The coefficient of static friction between the box and the incline plane is 0.5 and the coefficient of kinetic friction is 0.1 it is connected bya rope to a second box of mass 20kg that hangs vertically.

A. Sketch the forces acting on the boxes onto the diagram.

B. Draw a freebody diagram of the boxes.

C Find the acceleration of the hanging vertically from the pulley.

Here is a pic of the diagram:

2) A cart that has a mass of 100kg goes around a vertical loop at a constant speed of 10m.s. A person of mass 50kg is sitting in the cart.

A. Determine the force that the seat pushes on you with at the top of the loop.

B. Determine the force that the seat pushes on you with at the bottom of the loop.
