Determine the acceleration of the hanging weight

Reference no: EM13333463

A wheel rotates about a horizontal axis. It has an outer radius R1 = 18.8 cm and mass M1 = 5.12 kg. Attached to it concentrically is a hub (shown cross-hatched) of radius R2 = 5.35 cm and mass M2 = 1.12 kg. The axle has negligible radius and mass. Both the wheel and the hub are solid and have uniform density. Suspended from a massless string that is wound around the hub is a weight of mass m = 530 g.

a) What is the acceleration of the hanging weight after it is released?

( in m/s2)

b) When the weight has fallen a distance 64.9 cm, what is the kinetic energy of the rotating wheel?

(in J)
