Question

A water sprinkler covers the area shown in the figure.

Answer 1

A water sprinkler has a rotational motion in order to reach a broad area

from its stationary location.

The time it takes the sprinkler to reach the far right position is 36 seconds.

Reasons:

The given parameter are;

The angular speed of the water sprinkler, ω = 5° per second

Location where the sprinkler starts = The far left position

Required:

The time it takes the sprinkler to reach the far right position.

Solution;

The angle covered by moving from the far left to the far right, θ = 180°

Time required is given as follows;

$\omega = \mathbf{\dfrac{\theta}{t}}$

Therefore;

$t = \dfrac{\theta}{\omega}$

Which gives;

$t = \dfrac{180 ^{\circ}}{5^{\circ}/s} = 36 \, s$

The time it takes the sprinkler to reach the far right position, t = 36 seconds.
