Consider the car driving around a circular track. Once started, the driver maintains a speed of 45 m/h. Compare the
driver's velocity with his acceleration in this case.
The car is accelerating because it is changing direction but the velocity is
constant. the
A)
Eliminate
The car is traveling at a constant rate of speed so it is not accelerating and
the velocity does not change.
Acceleration is the change in velocity so the car is experiencing a change
in velocity and it is accelerating.
The car is traveling at a constant rate of speed so it is not accelerating but
the velocity changes because the direction the car travels is constantly
changing.

Amachinist turns the power on to a grinding wheel, at rest, at time t = 0 s. the wheel accelerates uniformly for 10 s and reaches the operating angular velocity 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. in this situation, the time interval of deceleration is closest to:
