The "Giant Swing" at a county fair consists of a vertical central shaft with a number of horizontal arms attached at its upper end as shown in (Figure 1). Each arm supports a seat suspended from a 5.00-mm-long rod, the upper end of which is fastened to the arm at a point RRR = 1.80 mm from the central shaft.
a)Make a free-body diagram of the seat, including the person in it. Draw the force vectors with their tails starting from the center of the dot. The location and orientation of your vectors will be graded. The exact length of your vectors will not be graded.
b)Find the time of one revolution of the swing if the rod supporting the seat makes an angle of θθtheta = 32.0 ∘with the vertical.

You are trying to slide a heavy trunk across a horizontal floor. The mass of the trunk is 85 kg, and you need to exert a force of 3.3 x 102 N parallel to the ground to make it just begin to move.
a). Determine the coefficient of static friction between the floor and the trunk.
After the trunk starts moving, you continue to push with this force. The trunk reaches a speed of 2.0 m/s after 5.0 s.
Calculate the coefficient of kinetic friction.
