Question

Pls help me with this problem!!

Answer 1

v = 19.6 m/s.

Step-by-step explanation:

Given that,

The radius of the circle, r = 5 m

The time period of the ball, T = 1.6s

We need to find the ball's tangential velocity.

The formula for the tangential velocity is given by :

`v=(2\pi r)/(T)`

Putting all the values in the above formula

`v=(2\pi * 5)/(1.6)\\\\v=19.6\ m/s`

So, the tangential velocity of the ball is 19.6 m/s. Hence, the correct option is (c).
