Horizontal projectiles

Question 1

A stone is thrown horizontally at 15 m/s from a cliff 44.1 m high. How far from the base of the cliff does it land, in m? (g = 9.8 m/s²; ignore air resistance)

Answer m

Question 2

Answer s

Question 3

A ball is thrown horizontally faster from the same height. What happens to its time of flight (no air resistance)?

• A. it gets shorter
• B. it never lands
• C. it stays the same, but it lands further away
• D. it gets longer

Question 4

A stone is thrown horizontally at 15 m/s from a cliff 44.1 m high. How far from the base of the cliff does it land, in m? (g = 9.8 m/s²; ignore air resistance)

Answer m

Question 5

A ball rolls horizontally off a table 2 m high. Ignoring air resistance, how long does it take to hit the floor, in s? (g = 9.8 m/s²; give 2 decimal places)

Answer s

Question 6

One ball is dropped and another is fired horizontally from the same height at the same moment. Which lands first (no air resistance)?

• A. They land at the same time
• B. It depends on their masses
• C. The dropped ball
• D. The fired ball

Question 7

A stone is thrown horizontally at 10 m/s from a cliff 44.1 m high. How far from the base of the cliff does it land, in m? (g = 9.8 m/s²; ignore air resistance)

Answer m

Question 8

A ball is kicked horizontally off a cliff 19.6 m high. Ignoring air resistance, how long does it take to reach the beach below, in s? (g = 9.8 m/s²; give 2 decimal places)

• A. a parabola
• B. a straight line
• C. a zigzag
• D. a circle

Question 10
