Hey everyone, first time poster here It's a really great forum though!
I can't seem to figure out this problem. If anyone could help that would be great.
1.A bicycle has wheels with a diameter of 0.650 m. It accelerates uniformly and the rate of rotation of its wheels increases from 177rpm to 275rpm in a time of 18.5 s. Find the linear acceleration of the bicycle.
I converted rpm to rad/s, and then found angular acceleration using a=vf-vi/t, but how do you find the linear acceleration given the diameter.
And there's also this one:
2.The tires of a car make 78.0 revolutions as the car reduces its speed uniformly from 92.5 km/hr to 55.9 km/hr. The tires have a diameter of 0.908 m. What was the angular acceleration?
