**Circular Motion Problem**

A ball of 500 g is attached to a string and starts from rest, speeding up with a constant tangential acceleration of \(3.00 \, \text{m/s}^2\) on a circular path of radius \(1.5 \, \text{m}\). The picture below is viewed from top down.

(a) **What is the angular acceleration of the ball?**

(b) **What is the ball’s angular speed 6.0 s after it starts?**

(c) **What is the ball’s tangential (linear) velocity at 6.0 s?**

(d) **What is the magnitude and direction of the ball’s centripetal force at 6.0 s? In this problem, is the tension of the string on the ball the same thing as the centripetal force?**

(e) **At 6 seconds the string is cut, what path would the ball follow (path A, B, or C) and at what speed? Before the ball was cut, what other force acted on the ball besides the tension (the centripetal force) on the ball? No, not the centrifugal force. Guess again.**

**Diagram Description:**
The diagram shows a hand holding a string attached to a ball moving in a circular path. The ball's motion is shown as being cut, and three potential paths (A, B, C) are depicted as possible trajectories the ball might follow once the string is cut. Path A is tangential to the circle at the point of release, while paths B and C are curved away from the circle in different directions.
