A car starts from rest and accelerates at a constant rate of 1.1 m/s2. If the radius of the car wheels is 29 cm, and the final angular speed of the car wheel is 48 rad/s, how far does the car travel

  • Physics - ,

    The final velocity is
    vf = R*w = 0.29*48 = 13.92 m/s. The time spent moving is
    Vf/a = 12.65 seconds.

    The distance travelled is (Vf/2)*(Vf/a)
    Vf^2/(2a)= 1

  • Physics (correction) - ,

    The "send" button got hit too soon

    Vf^2/(2a)= 176 m
