Block B is on a ramp inclined at a 45 degree angle; it is connected to block A via a string that runs over a pulley, so that A hangs vertically. You may assume that the string remains taut and does not stretch or break, and that the masses of the strings and pulley are negligible compared to the masses of A and B. You may also neglect friction throughout this problem. Block B has three times the mass of block A. At the time we are considering, block B is sliding up the ramp and slowing down. B.) draw vectors to indicate the net forces on block A and block B, with the correct directions and magnitudes. After drawing your vectors, explain how you figured out the correct directions and magnitudes.

A child is walking along the sidewalk at a constant speed of 1 m/s while pulling his dog sitting in a wagon. The dog has a mass of 30 kg and the wagon weighs 50 N. If the child pulls the wagon with a force of 60 N at an angle of 30°, what is the frictional force exerted by the wagon on the dog?
Two roofers are installing a new roof. Bob is sitting on the top of the roof that is angled at 23.5 degrees from the horizontal. Nate is sitting 4.1 m further down the roof. In order to get a box of shingles to Nate, Bob just slides the box directly down to him. If the coefficient of kinetic friction for the box and roof is 0.5, then with what speed should Bob initially push the box so that it slides to a stop right as it reaches the Nate?
Block A with a mass of 2.2 kg is at rest on a flat, horizontal, table 1 m from the edge. The table has a coefficient of kinetic friction of 0.308. A string is tied to Block A at one end, and the other is tied to Block B, which has a mass of 1.1 kg. While Block A is being held in place on the table, Block B is lowered over the edge of the table and allowed to hang freely. When Block A is released, it slides to the edge of the table. Assume that the string has an insignificant mass. How much time does it take for Block A to reach the edge of the table?

A 5-kg block is set into motion up an inclined plane (30°) with an initial speed of 8.0 m/s. There is friction between the block and the plane. The block comes to rest after traveling 3.0 m along the plane. Define the positive x-direction to be down the ramp.
A box, initially at rest, is pushed up a ramp that makes an angle of 15◦ with the horizontal as shown in the diagram. The magnitude of the pushing force is 8m newtons, where m is the mass of the box in kilograms. The force is in a direction parallel to and up the ramp. The coefficient of sliding friction between the box and the ramp is 0.25. Model the box as a particle and take the magnitude of the acceleration due to gravity to be g = 9.8 m s−2 . Express the four forces in component form in terms of unknown magnitudes where appropriate and find an expression for the resultant force acting on the box. Hence find the magnitude of the acceleration of the box, in m s−2

You are quite excited with the lesson in friction that you learned in Physics 1A that you decide to measure the coefficient of kinetic friction of surfaces. You try your idea on a glass surface and a glass cup (mass = 0.15 kg). You set the glass cup moving with an initial speed of 2.8 m/s. After travelling a length of 1 m, it stopped. What then is the coefficient of kinetic friction of the glass-glass surfaces?
