Q1. Sunlight enters a room at an angle of 31 above the horizontal and reflects from a small mirror lying flat on the floor. The reflected light forms a spot on a wall that is 2.2 behind mirror. If you now place a pencil under the edge of the mirror nearer the wall, tilting it upward by 5.0, how much higher on the wall is the spot?

Q2. A racing car travels on a circular track of radius 181 m, moving with a stable linear speed of 41.2 m/s.
