A projectile was launched from the top of a 25-m high building at a velocity of +35 m/s and at an angle of 28° with the horizontal. (a) How far is the projectile from the building (horizontally) by the time it reaches its maximum height? (Ans.: 51.82 m) (b) If the projectile lands on a hill 3 meters high from the ground, how long was the projectile airborne? (Ans.: 4.38 s) (c) If the projectile lands on a hill 3 meters high from the ground, how far is the hill from the building? (Ans.: 135.32 m)

A rugby player passes the ball 9.75 m across the field, where it is caught at the same height as it left his hand. At what angle was the ball thrown if its initial speed was 12.0 m/s, assuming that the smaller of the two possible angles was used? What other angle gives the same range? For the pass using the smaller of the two angles, how long is the ball in the air?
An NFL quarterback throws a pass, for which the launch angle is 29 degrees above horizontal, with an initial speed of 13.9 m/s, and the ball is caught at the same height at which is was released. How far horizontally does the ball travel, in meters, while it is in flight?
A horizontal projectile is shot with an initial velocity of 9.9 m/s from a height of 5.8 m above the ground. Neglecting air-resistance, what is the horizontal distance of the landing point (measured in meters from the base of the shooting point)?
What is the horizontal distance covered by a shotput if it has an initial velocity of 23 m/s at an angle of 44 degrees relative to horizontal with an initial height of release of 2.2 meters?
A sniper atop a building 150m high fired a bullet parallel to the horizontal with a speed of 1800km/h. Assuming that the bullet will hit its target, what would be the resulting range?
A ball is shot from the top of a building with an initial velocity of 18 m/s at an angle θ = 43° above the horizontal. If a nearby building is the same height and 61 m away, how far below the top of the building will the ball strike the nearby building? ( Choose upward as the positive y-direction and express the displacement with the sign of the result, which must be in units of meters and include 1 digit after the decimal point. Maximum of 5% of error is accepted in your answer. Take g=9.80 m/s2.)
