1. A bicycle slows down uniformly from v0 = 8.40 m/s to rest over a distance of 115m. Each wheel and tire has an overall diameter of 68.0 cm. Determine
(a) the angular velocity of the wheels at the initial instant (t=0),
(b) the total number of revolutions each wheel rotates before coming to rest,
(c) the angular acceleration of the wheel, and
(d) the time it took to come to a stop. Assumptions:wheels roll without slipping, the tire in in firm contact with the ground.
