A solid uniform disk of mass M = 8.8 kg and radius R = 21 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 = 113 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 1.2 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
