## Homework Statement

A motor car with wheels of 0.6,m diameter accelerates uniformly from 3 to 18m/s in 10 seconds.

Find:

a) the angular acceleration of the wheels

b) the number of revolutions made by each wheel during the speed change

## Homework Equations

A=v-u/t (angular equivilent with Alpha as acceleration etcetc)

## The Attempt at a Solution

My first thought was to change the 3m/s and 18m/s into Rad/s but I'm unsure how to go about doing that.

Then using A=v-u/t i assume the acceleration can be found

I have no clue how to attempt the second part.

Cheers.
