A bicycle has wheels with a diameter of 0.630 m. It accelerates uniformly and the rate of rotation of its wheels increases from 197 rpm to 300 rpm in a time of 22.5 s. Find the linear acceleration of the bicycle

  • physics -

    R=v₀•t
    t=R/v₀
    197 rpm = 197/60 =3.28 rev/s
    300 = 5 rev/s
    ω=ω₀+εt
    ε= (ω-ω₀)/t =(5-3.28)/22.5=0.0076 rad/s
    a = ε•R=0.0076•0.63=0.0048 m/s²

  • physics -

    you forgot to convert form from frequency to angular velocity where
    197rpm=3.28rev/s*2pi

    apart from that the steps are accurate
