Question

A stone attached to a string is whirled round in a horizontal circle with a constant speed of 10 m s Calculate the difference in the velocity when the stone is (i) at opposite ends of a diameter and (ii) in two positions A and B where angle AOB is 90 and O is the centre of the circle.

Answer 1

Answer:

When an object is moving with constant velocity then the particle is experiencing a centripetal force. The particle is then said to be moving with constant speed and angular rate of rotation. Therefore the particle will have a constant acceleration
