A boy wishes to throw a ball over a flat roofed school house that stands 12 m wide and 7.5 m high on level ground. Assuming that the ball will leave his hand at a height of 5 m above the ground,determine how far from the wall he should take his hand in order to make the ball clear the roof with least effort, that is, with minimum velocity.

Olympus Mons on Mars is the largest volcano in the solar system, at a height of 25 km and with a radius of 312 km. If you are standing on the summit, with what Initial velocity would you have to fire a projectile from a cannon horizontally to clear the volcano and land on the surface of Mars? Note that Mars has an acceleration of gravity of 3.7m/s2 .
The world long jump record is 8.95m. Treated as a projectile, what is the maximum range obtainable by a person if he has a take off speed of 9.5m/s? Assume the motion is on level ground and the angle is 45 degrees.
A regulation volleyball court measures L = 18.0 meters in length and d = 2.43 meters in height. A volleyball player hits the ball from a height of h = 1.50 m just over the backline, and the initial velocity of the ball creates an angle of q = 30° with the ground. At what initial speed must the ball be struck such that it barely clears the net?
A projectile is launched from ground level at an angle θ to the top of a cliff which is 195 m away and 155 m high. If the projectile lands right on the cliff edge 7.6 s after it is fired, find the initial velocity of the projectile.
If a human jumping can be treated as a projectile, what is the maximum range obtainable by a person if he has a take-off speed of 9.55 m/s? Assume negligible air resistance and the person begins and ends their jump at ground height.
Consider a projectile being launched with an initial speed of 58 m/s at a variety of initial angles. What is the range, in meters, of the projectile if it is launched at an angle of θ1 = 78.3°?
A rock is thrown horizontally from the top of a cliff 90m high , with a horizontal speed of 30 m/s . With what velocity does the rock land?
On level land, a youngster aspires to toss a ball over a flat-roofed schoolhouse measuring 12 meters wide and 7.5 meters high. Determine how far away from the wall he should stand to make the ball clear the roof with the least amount of effort, that is, with the lowest starting velocity, assuming the ball will leave his hand at a height of 1.5 m above the ground.

A punter kicks a football at an angle of 30 degrees with the horizontal at an initial speed of 15 m/s. Where should a punt returner position himself to catch the ball just before it strikes the ground?
A horizontal projectile is shot with an initial velocity of 8 m/s from a height of 7.4 m above the ground. Neglecting air-resistance, what is the magnitude of the final velocity (m/s)?
A basketball player who is 2.00 m tall is standing on the floor 10.0 m from the basket as in figure. If he shoots the ball at a 40.0° angle with the horizontal at what initial speed must he throw so that it goes through the hoop without striking the backboard? the basket height is 3.05 m.
