Chapter 6, Problem 5P
The “Giant Swing” at a county fair consists of a vertical central shaft with a number of horizontal arms attached at its upper end. (See Figure 6.28.) Each arm supports a seat suspended from a 5.00-m-long rod, the upper end of which is fastened to the arm at a point 3.00 m from the central shaft. (a) Make a free-body diagram of the seat, including the person in it. (b) Find the time of one revolution of the swing if the rod supporting the seat makes an angle of 30.0° with the vertical. (c) Does the angle depend on the weight of the passenger for a given rate of revolution?

Consider the roller coaster ride shown below. Here r1=6m and r2=16m. Imagine that the car is traveling with a constant speed of v=6.7m/s throughout the whole ride. If the mass of a child riding the car is m=35kg, determine the apparent weight of the child at point A. Express your answer using SI units with zero decimal place. Take g=9.80m/s2.
A block of mass m1 on a rough, horizontal surface is connected to a second mass m; by a light cord over a light frictionless pulley as shown in the figure. ('Light' means that we can neglect the mass of the cord and the mass of the pulley.) A force of magnitude Fis applied to the mass m4 as shown, such that m1 moves to the right. The coefficient of kinetic friction between m1 and the surface is p. Derive a formula for the acceleration of the masses. [Serway 5th ed., pg.135, Fig 5.14]
