Question

3. A motor cycle starts form rest and moves with a constant acceleration of 2.25 m/s2. What
is its angular acceleration, if the diameter of the motor cycle wheels is 750 mm​

Answer 1

Answer:

angular acceleration=6 rad/s

Explanation:

given acceleration=2.25 m/$s^{2}$ =2.25 x $10^{3}$mm/$s^{2}$

diameter=750mm

radius=375mm

angular acceleration(α)=?

    a=αr

    α=a/r

     α=(2.25x $10^{3}$)/375

   α=0.006 x$10^{3}$

   α=6 rad/s
