A rock is tied to the end of the string and swung in a circle with a radius of 1/2 meter. if the rock goes around once in 1/10 of a second what is the centripetal acceleration of the rock?

1974.4328 m/s²

Explanation:

r = Radius = 0.5 m

t = Time taken = 0.1 second

Rotational speed

The centripetal acceleration is given by

The centripetal acceleration of the rock is 1974.4328 m/s²
