To solve the problem, we need to find the velocity of the spot of light \( P \) on the wall when the angle \( \theta \) is \( 45^\circ \). Here’s a step-by-step breakdown of the solution: ### Step 1: Understand the Geometry We have a spotlight \( S \) rotating with a constant angular velocity \( \omega = 0.1 \, \text{rad/s} \) at a distance \( OQ = 3 \, \text{m} \) from the wall. The angle \( \theta \) is the angle between the line from the spotlight to the wall and the vertical line from the wall to the spotlight. ### Step 2: Relate the Angle to the Distance Using the tangent function in the right triangle \( OQP \): \[ ...
