Question

A car has wheels with tyres on, which are 75cm in diameter. The car is travelling at a constant speed of 60km/hr. If no slipping is observed between the wheels(tyres) and the road, calculate the angular speed and the acceleration of a stone wedged in the thread of the tyre
V = 60,000/3600s = 16.7 m/s.

C = pi*D = 3.14 * 0.75m = 2.36 m.

Va = 16.7m/s * 6.28Rad/2.36m=44.3 Rad/s.
