Question

"write an equation describing the angular velocity of the ball as a function of time"

Answer 1

`\omega=(\theta^c)/(t) =(l)/(r.t)`

Step-by-step explanation:

We know that the angular velocity is given by the rate of change in angular displacement. Where the angular displacement is in radians and time is in seconds for S.I. units.

Angular displacement is related to the length of arc traced per unit length of radius.

Mathematically:

`\omega= (\theta^c)/(t)`

and

`\theta^c=(l)/(r)`

where:

`\theta^c=` angle measured in radians

`l=` length of arc traced

`r=` radius of the circular path

`t=` time taken to trace the angle
