Hi, I am working on the following problem:
As you drive down the road at 17 m/s you press on the gas pedal and speed up with a uniform acceleration of 1.12m/s2 for 0.65s. If the tires on your car have a radius of 33cm , what is their angular displacement during the period of accceleration?
This is what I did so far,
(1.12m/s^2) / 0.65s = 1.72 m/s acceleration
then 17m/s - 1.72 m/s = 15.28
15.28/.33m = 46 displacement?
Im not sure this was right??
