Question

A car initially traveling at 26 m/s hits the brakes, generating a constant acceleration of -2 m/s2. Under this acceleration, the car comes to a rest. If the tires have radii of 0.33 m, how many revolutions does each tire make as the car slows down and stops? Assume no skidding.

Answer 1

s=v²/2•a =26²/2•2=…
N=s/2•π•R=..
