Is it possible for speed to be constant while acceleration is not zero? Give an example of such a situation.
A. An object moving in a circle with uniform speed has no change of speed but it has acceleration. It has centripetal acceleration towards the center of the circle.
B. An object moving in a triangle with non-uniform speed has no change of speed but it has acceleration. It has scalar acceleration towards the center of the triangle.
C. An object moving in an ellipse with uniform speed has no change of speed but it has momentum. It has centripetal acceleration towards the tangent of the circle.
Ans: A. An object moving in a circle with uniform speed has no change of speed but it has acceleration. It has centripetal acceleration towards the center of the circle.

Constant Angular Acceleration: A machinist turns on the power on to a grinding wheel at time t = 0 s. The wheel accelerates uniformly from rest for 10 s and reaches the operating angular speed of 96 rad/s. The wheel is run at that angular velocity for 40 s and then power is shut off. The wheel slows down uniformly at 1.5 rad/s2 until the wheel stops. For how long a time after the power is shut off does it take the wheel to stop?
A. 64 s B. 62 s C. 66 s D. 68 s E. 70 s
