Part A Two metal disks, one with radius R1 = 2.40 cm and mass M = 0.900 kg and the other with radius R2 = 5.05 cm and mass M2 = 1.70 kg , are welded together and mounted on a frictionless axis through their common center. A light string is wrapped around the edge of the smaller disk and a 1.60 kg block is suspended from the free end of the string. What is the magnitude of the downward acceleration of the block after it is released? Take the free fall acceleration to be 9.80 m/s?. a = m/s? Submit Request Answer Part B Repeat the calculation of part (a), this time with the string wrapped around the edge of the larger disk. Take the free fall acceleration to be 9.80 m/s?. ? a = m/s² Submit Request Answer

A tennis ball connected to a string is spun around in a vertical, circular path at a uniform speed. The ball has a mass m = 0.173 kg and moves at v = 5.39 m/s.

Problem 1 Seeing Double Two blocks are connected to one another with ropes as shown on a frictionless table. The m block is a distance r from the center while the 2m block is a distance r from the center. They have an angular speed of w. (a) What is the linear speed of each block? (b) Find the tension in each rope. (c) If the masses complete a circle 8 times every second, what is w in rad/s? G
