Question

A wheel makes 30 revolutions per minute find the Radian measure of the angle described by one of the spokes of the wheel in 1/2 second​

Answer 1

Step-by-step explanation:

The wheel rotates 30 revs per minute

So in half a second it will rotate 30/(60*2)=.25 revs

Again 1 rev= 2pi rad

So .25 rev = pi/2 rad

As any point of the wheel will have same angular displacement(assuming a rigid wheel) the spoke will also rotate by pi/2 rad.

Thanks.
