A solid disk (mass = 5 kg, R=0.6 m) is rolling across a table with a translational speed of 9 m/s.
a.) What must the angular speed of the disk be?
rad/s
b.) What is the rotational kinetic energy of the disk?
J
c.) What is the total kinetic energy of the disk?
J
d.) The disk then rolls up a hill of height 2 m, where the ground again levels out. Find the translational and rotational speeds now.
m/s
rad/s
