Hi, Im working on the following problem:(adsbygoogle = window.adsbygoogle || []).push({});

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??
