| In a particular laboratory experiment, a spring gun placed on a table fires a steel ball horizontally outward. A student determines that the ball starts 1.0 m above the floor and travels 2.7 m before striking the floor. Determine the time that the ball is in the air and the initial velocity of the ball. | 0.45 s; 5.98 m/s |
| A ball is thrown horizonally with a velocity of 20 m/s from a tower 40 m high. Find the time of flight and the horizontal range. | 2.86 s; 57.1 m |
| A bullet has a speed of 350 m/s as it leaves a rifle. If it is fired horizontally from a cliff 6.4 m above a lake, what is the horizontal range of the bullet? | 400 m |
| A golf ball is driven horizontally with a speed of 40 m/s from a cliff 25.6 m high, and it lands on a level plain below. How long is the ball in the air? How far from the base of the cliff does it strike the ground? | 2.29 s; 91.4 m |
| A rock is thrown horizontally with an initial velocity of 8 m/s from the top of a building 60 m high. How long does it take the stone to reach the bottom? How far from the base of the building does the rock strike the ground? | 3.50 s; 28.0 m |
| A stone is thrown horizontally outward from the top of a bridge. The stone is released 19.6 m above the street below. The initial velocity of the stone is 5.0 m/s. Determine the total time that the stone is in the air. | 2 s |
| A projectile is fired with an initial speed of 113 m/s at an angle of 60 degrees above the horizontal from the top of a cliff 49 m high. Determine the total time it is in the air and the horizontal range of the projectile. | 20.5 s; 1156 m |
| A punter kicks a football with a velocity of 80 ft/s at an angle of 36.9 degrees with the horizon. Find the time during which the ball rises, how high it goes, and the length of the kick. The value of g for this problem is -32 ft/s^2. | 1.5 s; 36.1 ft; 192 ft |
| A boy kicks a soccer ball off the ground, giving it a speed of 18 m/s at an angle of 53.1 degrees with the horizontal. Find how long the ball is in the air, how high it goes, and the horizontal distance it traverses before it strikes the ground. | 2.94 s; 10.6 m; 31.7 m |
| A golf ball on a level fairway is given an initial velocity of 50 m/s at an angle of 35 degrees with the horizontal. If air friction is neglected, find how long the ball is in the air, how high it goes, and how far away it lands. | 5.85 s; 42.0 m; 240 m |
| A person in a hot-air balloon throws a ball at 40 degrees to the horizon at 10 m/s. If the ball is launched at a height of 100 m, where will it land? | 40.0 m |
