In the figure we see a mass m2=0.2 kg undergoing circular motion
of radius 0.5 m on a frictionless table. The second mass, m1=0.3

A small object of mass m1 moves in a circular path
A small object of mass m1 moves in a circular path of radius r on a frictionless horizontal tabletop. It is attached to a string that passes through a frictionless hole in the center of the table. A second object with a mass of m2 is attached to the other end of the string. Derive an expression for r in terms of m1, m2, and the time T for one revolution. (Use any variable or symbol stated above along with the...

Understand how to find the equation of motion of a particle undergoing uniform circular motion. Consider a particle--the small red block in the figure--that is constrained to move in a circle of radius R. We can specify its position solely by θ(t), the angle that the vector from the origin to the block makes with our chosen reference axis at time t. Following the standard conventions we measure θ(t) in the counterclockwise direction from the positive x axis. (Figure 1)...

4. Determine the motion of the center of mass using Allyson's Method. In the motion diagram below mt and m2 make up a system of two particles. Assume that mi is moving in the +x direction as indicated by the equally spaced interval of dots and that m2 is stationary. If the masses are equal (m1 m2) the velocity of the center of mass is found by first connecting a series of lines from each successive "m1 position dot" to...
