Answer:
v = 1.26 m/s
Step-by-step explanation:
Given that,
The radius of the circle, r = 20 cm = 0.2 m
The centripetal acceleration of the object, a = 8 m/s²
We need to find the tangential velocity of the object. We know that the formula for the centripetal acceleration is given by :

So, the tangential velocity of the object will be 1.26 m/s.
