1. A physics student is doing an experiment at the top of the school football bleachers, where she is going to throw an egg horizontally with a speed of 10 m/s. At the instant she throws the egg, she accidentally knocks over another egg which falls an equal distance to the ground. Which egg hit the ground first?

• The dropped egg

• The thrown egg

• Both will hit the ground at the same time

1. A ball is thrown horizontally at a speed of 20 m/s from the top of a cliff. As the speed of the ball is decreased, the time required for the ball to fall 30 m will

• Decrease

• Increase

• Remain the same

1. A ball is tossed straight upward in an airplane doing 500 mi/h in a straight line at constant altitude. When the ball lands in the cabin its position relative to the person who tossed it will be

• (1) Farther toward the back of the cabin depending upon the plane’s speed

• (1) Farther toward the front of the cabin depending on the plane’s speed

• (1) Right back down on the person who tossed it straight upward

• (1) Farther toward the back of the plane if the ball is light, but farther toward the front if the ball is heavy
