Question

a small cylinder rests on a circular turntable that is rotating clockwise at a constant speed. which set of vectors gives the direction of the velocity v and acceleration a of the cylinder, and the net force σf that acts on it. cylinder rotation of turntable turntable (top view) (1) (2) (3) (4)

Explanation:

Step1: Analyze velocity direction

The velocity of an object moving in a circular - path is tangent to the circle at the point of the object's position. Since the turntable is rotating clock - wise, the velocity vector $\vec{v}$ of the cylinder is tangent to the circular path in the clock - wise direction.

Step2: Analyze acceleration and force direction

For an object moving in a uniform circular motion, the centripetal acceleration $\vec{a}$ and the net force $\sum\vec{F}$ acting on it are directed towards the center of the circle.
