Question 1
When the center of a bicycle wheel has linear velocity
relative to the ground, the velocity relative to the ground of point
P' at the top of the wheel is
◦
0.
◦
.
◦
.
◦
.

.
Question 2
When the sum of the external forces and the sum of the external torques on a body are both zero, we can conclude that
◦
the body is moving at constant velocity but is not rotating.
◦
the body is rotating at constant angular velocity but has no linear velocity.
◦
the body has neither linear nor angular velocity.
◦
the body may have constant linear or angular velocity, but not both simultaneously.
◦
the body may have constant linear or constant angular velocity, or both simultaneously.
