Question

a stone attached to 1m long string is moving with the speed of 5ms in a circle find the centripetal acceleration of the stone​

Answer 1

The centripetal acceleration of the stone is 5 m/s²

Step-by-step explanation:

The length of the string to which the stone is attached, r = 1 m

The speed with which the string is rotated, v = 5 m/s

The centripetal acceleration,
`a_c`, is given as follows;

`a_c = (v^2)/(r)`

Therefore, the centripetal acceleration of the stone found as follows;

`a_c = ((5 \ m/s)^2)/(1 \ m) = 5 \ m/s^2`

The centripetal acceleration of the stone,
`a_c` = 5 m/s².
