A car starts from rest and accelerates uniformly to a speed of 50km/h in 18s. If the wheels of the car are 70cm in diameter. Calculate;
a.The final angular velocity of the wheels
b.angular acceleration

  • Physics -

    Vfinal = 50 km/h = 13.889 m/s

    a = acceleration rate = 13.889/18
    = 0.7716 m/s^2

    a) Final W = Vfinal/R = 39.68 rad/s
    b) Angular acceleration = a/R
    = ___ rad/s^2
