Estimate what is the kinetic energy of the rotating wheel

Reference no: EM13565852

A wheel rotates about a horizontal axis. It has an outerradius R1= 21.2 cm and mass M1=4.51 kg. Attached to itconcentrically is a hub of radius R2= 4.70 cm and mass M2 = 1.16kg. The axle has negligible radius and mass. Both the wheel and thehub are solid and have uniform density. Suspended from a masslessstring that is wound around the hub is a weight of mass m = 484 gm.

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

b) when the weight has fallen a distance of 73.1 cm, what is the kinetic energy of the rotating wheel?
