Question
A block of mass m is attached to a pulley disc of equal mass m, radius r by means of a slack string as shown. The pulley is hinged about its centre on a horizontal table and the block is projected with an initial velocity of 5 m/s. Its velocity when the string becomes taut will be
- 3 m/s
- 2.5 m/s
- 5/3 m/s
- 10/3 m/s
The correct answer is: 5/3 m/s
