# Projectile Motion Quiz

1. Devondra is using a ladder to pick oranges from the top of a tree in her yard. She drops an orange from a height of 2.6 m, and it falls to the ground below. Neglecting air resistance, how long did it take the orange to hit the ground below.

2. Aimee’s airplane is flying horizontally with a constant velocity of 112 m/s northward at an altitude of 925 m. The airplane is in remote, mountainous logging region, and Aimee, the pilot, releases a mail package for the loggers below. Neglecting air resistance, calculate the time for the package to hit the ground.

3. James is in the final stages of Marine Wilderness Survival Training. He is holding his rifle horizontally 1.6 meters above the ground when he fires a bullet for the first time. The initial speed of the bullet as it leaves the rifle is 1100 m/s. Neglecting air resistance, calculate the time needed for the bullet to strike the ground.

4. James is in the final stages of Marine Wilderness Survival Training. He is holding his rifle horizontally 1.6 meters above the ground when he fires a bullet for the first time. The initial speed of the bullet as it leaves the rifle is 1100 m/s. Neglecting air resistance, calculate the horizontal range of the bullet.

5. Paul and Josue are helping a neighbor replace the shingles on his house. Paul is standing on the edge of the roof at a height of 3.6 m when he accidentally kicks a hammer off the roof. Neglecting air resistance and noting that the hammer is kicked horizontally, what is the fall time of the hammer?

6. Paul and Josue are helping a neighbor replace the shingles on his house. Paul is standing on the edge of the roof at a height of 3.6 m when he accidentally kicks a hammer off the roof. Neglecting air resistance, if Paul’s kick gave the hammer an initial horizontal speed of 3.5 m/s, how far out does the hammer hit the ground.

7. The local police are investigating an accident involving a car that drove straight off a 52 m cliff. If the car landed 148 m from the base of the cliff, how fast was the car traveling as it went over the cliff?
