Question

A ball of mass 4.0 kg is attached to the end of a 1.2 m long string and whirled around in a circle that describes a vertical plane. 1. What is the minimum speed that the ball can be moving at and still maintain a circular path? (3 marks) 2. At this speed, what is the maximum tension in the string? (3 marks)

Step 1

Step 2: The tension in the string provides the centripetal force, so we can set the tension equal to the centripetal force: \[ T = \frac{mv^2}{r} \] Step 3: We can solve for the minimum speed by rearranging the equation: \[ v = \sqrt{\frac{Tr}{m}} \] Step Show more…
