Question

. A stone is tied to one end of a string and whirled in a horizontal circle of radius 1 m at 20 revolutions

per minute. Calculate the angular velocity and linear speed of the stone. Also find the centripetal

acceleration.​

Answer 1

Explanation:

angular veocity =2Πx20 rad/min

=40Π rad/min

linear velocity=rxangular velocity

=1x40Π m/min

=.67Π m/sec
