Question

A mechanic alters the lighthouse to make the light rotate in such a way that is reflection travels north word along the wall at a constant rate of 100 ft./s how fast in radians per second is the beam of light rotating when the lights reflection is 100 feet north of the point on the wall that is closest to the lighthouse

Answer 1

The correct solution will be "1 Rad/sec".

Explanation:

The given value is:

Velocity (V)

= 100 ft./sec

As we know,

Angular velocity,

⇒
`\omega=(V)/(R)`

On substituting the values, we get

⇒
`=(100)/(100)`

⇒
`=1 \ Rad/sec`
