A wheel of radius 10 cm is turning at a rate of 5 revolutions per minute. Calculate : the angle subtended at the centre by the minor arc.

Complete question:

A wheel of radius 10 cm is turning at a rate of 5 revolutions per minute.

Calculate  the angle subtended at the centre by the minor arc after 1 second.

the angle subtended at the centre by the minor arc is 30⁰

Step-by-step explanation:

Given;

radius of the wheel, r = 10 cm = 0.1 m

angular speed of the when, ω = 5 rev/min

duration of the motion, t = 1 second

Determine the angular speed in radian per second,

After 1 second, the angular distance turned by the wheel is calculated as;

Therefore, the angle subtended at the centre by the minor arc is 30⁰
