Projectile Motion Practice Projectile Motion 1. If a girl kicks a soccer ball horizontally from a hill that is 20 meters high at 15 m/s, how far away will it land?

2. How fast would you have to run off of a 10 meter diving platform to land 10 meters out into the pool?

3. A rifle with a muzzle velocity of 100 m/s is fired horizontally from a tower. Neglecting air resistance, where will the bullet be 1 second later? (How far will it fall vertically? How far will it move horizontally?)

4. A soccer ball was kicked on a horizontal field. The initial vertical component of the soccer ball was 15 m/s and the initial horizontal component was 8 m/s. a) What was the vertical component of the balls velocity just before it hit the ground? b) What was the horizontal component of the balls velocity just before it hit the ground?

5. A plane drops a package of emergency rations to a stranded party of explorers. The plane is traveling horizontally at 40.0 m/s at 100 m above the ground. Find a) where the package strikes the ground relative to the spot it was dropped and b) the velocity of the package just before it hits the ground.

6. A Stealth Bomber is flying straight and level at 1500 m above the ground and at a velocity of 600 m/s. How far ahead of his target (on the x-axis) will the bomber need to release his bombs in order to hit its target?
