-A mass of 12.0 kg is placed on a table. A string is tied to the mass and run over a pulley to a hanging mass. If the coefficient of static friction between the mass on the table and the table is 0.342, what is the minimum value of the hanging mass that will start the system moving?

-A child wearing a slippery snowsuit is sitting on a sled such that the coefficient of static friction between the suit and the sled is 0.112. What is the maximum acceleration possible for the sled before the child slips off?

- The force of gravity on a basketball is 16 N [down]. You push the ball with a force of 26 N [up 45º right]. Calculate the net force on the ball. If the mass of the basketball is 0.625 kg, what is its acceleration?

-The tightrope walker gets tired and decides to stop for a rest. During this rest period, she is in equilibrium. Show the forces acting on the ropes and the tightrope walker.

- A helicopter drops a cable which is attached to a load. The cable is partially reeled in, and the helicopter flies east. Air resistance causes the load to swing backwards such that it makes an angle of 20.0° with the vertical. Draw a FBD of the situation
