Question

A solid uniform disk of mass M = 9.1 kg and radius R = 23 cm rests with its flat surface on a frictionless table (i.e., the axis of the cylinder is perpendicular to the table.) The diagram shows a top view. A string is wrapped around the rim of the disk and a constant force of F = 118 N is applied to the string. The string does not slip on the rim.

a) What is the acceleration of the center of mass?
a = m/s2

b) What is the angular acceleration about the center of mass?
a = rad/s2

The next 5 questions refer to a time 1.1 s after the force is first applied.
c) How far has the disk moved?
d = m

d) Through what angle has the disk turned?
q = rad

e) What is the translational speed of the disk?
v = m/s

f) What is the angular velocity about the center of the disk?
w = rad/s

g) What is the total kinetic energy of the disk?
KE = J
