A 15 kg flywheel has all its mass around its outer rim. A string is wrapped around it and a m = 3.7 kg weight is hanging on the string. The flywheel has radius R = 0.25 m.

a) When the 3.7 kg weight is dropping with a speed of 1.7 m/s, what is the angular velocity of the flywheel?

w = ?? rad/s

b) When the 3.7 kg weight is moving with a speed of 1.7 m/s, what is the kinetic energy of the entire system?

K.E. = ?? J

c) If the system started from rest, how far has the weight fallen?

hfall = ?? m

d) What is the angular acceleration at this point?

a = ?? rad/s2
