Starting from rest, a person pedals a bicycle such that the angular acceleration of the wheels is a constant 1.40 rad/s2. The bicycle wheels are 35.0 cm in radius. What is the magnitude of the bicycle's linear acceleration (in m/s2)? What is the angular speed of the wheels (in rad/s) when the linear speed of the bicyclist reaches 11.6 m/s? How many radians have the wheels turned through in that time? How far (in m) has the bicycle traveled in...

A bicycle wheel with a radius of 0.40 meters has a mass of 2.25 kg mostly :concentrated near the rim. Treat the wheel as a ring of mass, I_ring = m r^2, rotating at 146 rpm (15.3 rad/s). Brakes on the rim slow the wheel to a stop at a constant angu acceleration. the angular acceleration, a, of the wheel if it is brought to rest in 5 seconds is the moment of inertia of the wheel, I, is closest...

Tutorial Exercise A rotating wheel requires 13.0 s to rotate 44.0 revolutions. Its angular velocity at the end of the 13.0-s interval is 89.0 rad/s. What is the constant angular acceleration (in rad/s) of the wheel? Step 1 Converting to radians, we find that the angular displacement Δθ undergone by the wheel in 44.0 revolutions is t rad. 1 rev Submit Skip (you cannot come back)
