Q1. A slide projector needs to create a 94.9 cm high image of a 2.07 cm tall slide. The screen is 284 cm from the slide. Suppose that it is a thin lens.

Q2. An airplane is flying with a velocity of 81.6 m/s at an angle of 18.0 above the horizontal. When the plane is the distance 123 m directly above a dog that is standing on level ground, a suitcase drops out of the luggage compartment. How far from the dog will suitcase land?
