Consider a point on a bicycle wheel as the wheel turns about a fixed axis,neither speeding up nor slowing down.Compare the linear and angular accelerations of the point.
A)Both are zero.
B)Only the angular acceleration is zero.
C)Only the linear acceleration is zero.
D)Neither is zero.

Since the wheel is turning at a constant rate, the angular acceleration (rate of change of angular velocity) is zero. However, the direction of the linear velocity of a point on the wheel is constantly changing as the wheel turns, which means there is a centripetal acceleration towards the center of the wheel, indicating that the linear acceleration is not zero.
