Time Allowed: 20 minutes Question: The search light shown in Figure 1 casts a spot of light along the face of the wall that is located 120m from the searchlight. Determine the magnitude of the velocity and acceleration at which the point appears to travel across the wall at the instance when 0 = 40 degrees. The searchlight is rotating about Z axis at the constant rate of de/dt = 2 rad/s Wall . 120 m Figure 1 de/dt 2 rad/s Solution ---
