Question
The tires of a car make 63 revolutions as the car reduces its speed uniformly from 94.0 km/h to 58.0 km/h. The tires have a diameter of 0.88 m. What was the angular acceleration of each tire? And If the car continues to decelerate at this rate, how much more time is required for it to stop?
Answers

wf^2=wi^2+2*angularacceleration*63*2PI
to get wf and wi, speed/(2PI*d) = w
change speed to m/s
to get wf and wi, speed/(2PI*d) = w
change speed to m/s
