How Does Acceleration Affect a Car's Tire Rotation and Speed?

[johnnyyy]

Homework Statement

If a car with 30.0 cm tires is accelerating at 0.75 m/s^2, what is the angular acceleration? How fast will the tires be spinning from rest if the car accelerates for 1.50 minutes? And finally how fast will that be linearly?
T=90 seconds
R=.3 m

Homework Equations

Vt=rw

a=wf-wi/t

W=ø/t

The Attempt at a Solution

Homework Statement

Will a car traveling at exactly 20 mph around a corner have a tangential acceleration? Centripetal acceleration? Explain.

It is a poorly worded question, but it appears to be asking you to find the angular acceleration of the wheels, not the car.

you are given dv/dt, but you need to find d\omega/dt. Use v= \omega r
