The tangential velocity of the ball is 0.63 m/s.
Tangential speed is the linear component of the speed of any object moving along a circular path.
v = ωr
where;
At a given radius of the circle = 0.3 m
Let the number of revolution per min = 20 rev/min
[tex]\omega = 20 \frac{rev}{\min} \times \frac{2\pi \ rad}{1 \ rev} \times \frac{1 \min}{60 \ s} = 2.1 \ rad/s[/tex]
v = ωr
v = 2.1 x 0.3
v = 0.63 m/s
Thus, the tangential velocity of the ball is 0.63 m/s.
