A cyclist traveling at 5 m/s uniformly accelerates up to 10 m/s in2.0 Sec. Each tire of the bike has a 35 cm radius, and a smallpebble is caught in one of them.
(a) what is the angular acceleration of the pebble during those twoseconds ?
(b) Through what angle does the pebble revolve ? How far does thepebble travel during that accelerating interval?
