Question

A. A car is moving to the right with cruise control on. Assume that the tires are not slipping. In which direction are the tires' angular acceleration pointing?

B. A car is moving to the right with cruise control on. Assume that the tires are not slipping. In which direction are the tires' angular velocity pointing?

C. A car to moving up a 45 degree ramp (pointed upward and to the left) while slowing down. Assume that the tires are not slipping. In which direction are the tires' angular velocity pointing?

D.

A car to moving up a 45 degree ramp (pointed upward and to the left) while slowing down. Assume that the tires are not slipping. In which direction are the tires' angular acceleration pointing?

Explanation / Answer

A)Tires angular acceretion is perpendicular to the plane in which direction of rotation of tires takes place that is toward the cruise control.

B) Tires angular accereration is in clockwise directions

C)Now tires angular velocity is again clockwise direction.

D) Again tires angular acceleration is perpendicular to plane in which direction of tires takes place but this time direction is away from cruise control.
