1. The problem statement, all variables and given/known data A bicycle has wheels with a radius of 0.295 m. It accelerates uniformly and the rate of rotation of its wheels increases form 209 rpm to 265 rpm in a time of 20.7 s. What is the linear acceleration of the bicycle? ω=angular vel. α=angular accel. 2. Relevant equations rev/min*2π*1/60s= rad/s α=Δω/Δt arad=ω2*r atan=r*α atotal=√arad2+atan2 3. The attempt at a solution First changed rpm to radian/s so ω1=21.89 radian/s and ω2=27.75 radian/s For α=Δω/Δt=(27.75-21.89)/20.7s=0.283 radians/s2 Then got atan=0.295 m*0.283 radians/s2=0.0835 m*radians/s2 But I don't know if I should use ω1 or ω2 for the arad?? Do you use both and add them together to use for atotal or the change in arad? Also, do I have to multiply the final total accel by 2 since there are two wheels?
