A stone tied to the end of the string 100 cm long is whirled in a horizontal circle with a constant speed. If the stone makes 30 revolution in 15 s. Calculate the magnitude and direction of acceleration of the stone.

Text Solution

Verified by Experts

The correct Answer is:
`157.76 m//s^(2)`, towards the centre
`a=r(2pin)^(2) =1 xx 4pi^(2) xx 2^(2) = 157.76 m//s^(2)`
