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
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
