A cyclist who is riding a bike, whose wheels have a radius of r, is moving with constant speed v, along a flat straight road. The cyclist realizes that there is a single rock stuck between the threads of his tires that is causing the bike to vibrate violently. How frequently do the vibrations caused by the rock occur

Explanation:

A cyclist riding a bike whose wheels have a radius of r, moving with constant speed v along a flat straight road.

The frequency of the vibrations is the same as the frequency of the rotation of the wheel and this can be represented as below

V = R(w )     where ; w =

a longitudinal wave moves energy that is to the direction of the wave’s movement. - true
