Tangential Acceleration

  1. Feb 2, 2014 #1
    1. The problem statement, all variables and given/known data
    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

    2. Relevant equations
    Vt=rw

    a=wf-wi/t

    W=ø/t


    3. The attempt at a solution

    1. The problem statement, all variables and given/known data
    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
