your car tire has a radius of .4 m and is rotating at 3.5 rev/s, when suddenly you press hard on the accelerator. after traveling 200 m, the tire's rotation has increased to to 6.0 rev/s. what was the tires angular acceleration?

angular acceleration = increase in revolutions / second / second
u1 = 3.5 rev/sec
v1 = 6.0 rev / sec
so w = +2.5 rev / second OVER TIME t

so what was the time it took?

jack1 · Answer

if the radius is 0.4 m, how long did it take to travel 200 meters
asked another way
if the radius is 0.4 m, how many revolutions is 200 meters?

jack1 · Answer

do you know and understand the equations for angular motion?
