Unformatted text preview: A mass m 1 undergoes circular motion of radius R at speed v 1 on a horizontal frictionless table, connected by a massless string through a hole in the table to a second mass m 2 , as pictured. If m 2 is stationary, find (a) the tension in the string and (b) the period of the circular motion. Essential University Physics, J. Wolfson 2/09/10 Uniform Circular Motion, Q2 and Q3 (a) Find tension in string. (b) Find period of rotation. How many forces does the hanging mass (m 2 ) feel? How many forces does the moving mass (m 1 ) feel? A. 0 B. 1 C. 2 D. 3 E. 4 Complete on Board Essential University Physics, J. Wolfson...
