A bike of wheel radius. 40 cm at its highest speed its meter show 300RPM.then evalute the speed of the bike on this reading

Circumference = pi*2r = 3.14 * 80 = 251.3 cm. = 2.513 m.

V=300rev/min * 2.513m/rev * 1min/60s =
12.57 m/s. = Linear speed.

Va = 12.57m/s * 6.28rad/2.513m=31.4rad/s
= Angular speed.
