A projectile is thrown from the top of a building with an initial velocity of 300m/s in the horizontal direction. If the top of the building is 30m above the ground, how fast will the projectile be moving just before it strikes the ground?

An athlete in a high jump event is running at 5.3 m/s directly toward the high-jump bar when he jumps into the air to jump over the bar. He maintains his horizontal velocity. (Hint : The athlete is now on a projectile trajectory to reach the high-jump bar) (a)What vertical velocity (in m/s) does he need in order to just rise 65 centimeters above the ground? (b)How far (in m) from the bar (measured in the horizontal direction) must he start his jump to reach his maximum height at the same time as he reaches the bar?

Standing at the edge of a 70 meter high cliff, Failee throws a rock with a horizontal velocity of 21 m/s. How long is the rock in the air, and how far does it travel horizontally before striking the water ?

If the height of the water slide is h = 3.8m, and the person's initial speed at the top is 0.70m/s , what is the horizontal distance between the base of the slide and the splashdown point of the person?
