1.) A ball is thrown horizontally from a height of 1 m and lands 5 m away. a. What is the time of flight of the ball?

b. What is the initial velocity of the ball?

2.) A potato gun is fired horizontally from a height of 1.5 meters with the potato launched at 25 m/s.

a. What is the time of flight of the potato?

b. How far from the gun will the potato land?

3.) A water park is designing a new water slide that finishes with the rider flying horizontally off the bottom of the slide. The slide is designed to end 1.2 m above the water level, and the average rider is estimated to leave the bottom of the slide at 25 m/s. How far will the rider fly through the air before hitting the water?

4.) A marble rolls horizontally off a table that is 0.8 m tall. If the marble lands 0.6 m from the base of the table, what is the initial velocity of the marble?

5.) The launch velocity of a toy car launcher is determined to be 5 m/s. If the car is to be launched from a height of 0.5 m, where should a target be placed so that the toy car lands on it?

6.) A stunt car traveling at 20 m/s flies horizontally off a cliff and lands 39.2 m from the base of the cliff. How tall is the cliff?

7.) A blow dart is fired horizontally from a height of 1.2 meters. If the dart hits a target that is 0.6 m high and 12 m away, what is the initial velocity of the dart?

8.) A B-52 bomber jet flies at a horizontal velocity of 286.2 m/s and at an altitude of 7500 m above the ground. How far away horizontally should a payload be dropped to land on a target?
