Question

a stone is tied to one end of a string and whirled in a horizontal circle of radius 0.5m at 120 rpm calculate the angular velocity of the stone and the centripetal acceleration on it​

Answer 1

Answer:

Explanation:

120 rpm=120 round per minute=2 round per second

frequency(n)=2

angular velocity (w)=2 pi n=2 pi *2=12.56

centripetal acceleration=w^2 * r=(12.56)^2*0.5=78.87
