Answer:
The angular speed of rolling ball is 3.23 rad/sec.
Explanation:
Given that,
Radius = 1.95 cm
Speed = 6.30 cm/s
Suppose, we need to find the angular speed of rolling ball
We need to calculate the angular velocity
Using formula of angular velocity
[tex]v = r\omega[/tex]
Where, r = radius
[tex]\omega[/tex] = angular velocity
Put the value into the formula
[tex]\omega = \dfrac{v}{r}[/tex]
[tex]\omega =\dfrac{6.30}{1.95}[/tex]
[tex]\omega=3.23\ rad/sec[/tex]
Hence, The angular speed of rolling ball is 3.23 rad/sec.
