Acoin completes 18 spins in 12 seconds. the centripetal acceleration of the edge of the coin is 2.2 m/s2. the radius of the coin is 0.0250.0372.18.0

Radius of the coin, r = 0.025 m

Explanation:

It is given that,

Centripetal acceleration, a = 2.2 m/s²

A coin completes 18 spins in 12 seconds. So, its frequency will be :

Centripetal acceleration is equal to :

Since, ω = 2πf

r = 0.025 m

So, the radius of the coin is 0.025 meters. Hence, this is the required solution.

the displacement produced by the body.  

the amount of force subjected to the body.  

the angle between the direction of force and displacement
