velocity bicycle wheels
Physics question about riding a bike?
One person has a bicycle, and the wheels have an angular velocity of +20.5 rad / s. Then the brakes are applied and the bike is set to a uniform stop. During braking, the angular displacement of each wheel is +14.5 revolutions. (A) How long will it take the bike to come to rest? * __s (B) What is the angular acceleration of each wheel? * __rad/s2
The angular displacement θ = 14.5 * 2pi rad. The relationship of displacement, velocity, acceleration and time in the rotation are similar to those in the translation. Translation: x = at ^ 2 / 2, v = Rotation on: θ = αt ^ 2 / 2, ω = αt From this you can borrow α and θ and ω t is given. θ = ωt / 2 ==> t = 2θ / ω α = ω / t
