1.Easy

A stone is thrown horizontally from the top of a 65 m high wall and lands 12 m from the foot of the wall. Ignore air resistance and use g = 9.81 m/s². Find the launch speed v₀.

h = 65 mx = 12 mg = 9.81 m/s²

v₀ = m/s

2.Easy

A ball is thrown horizontally at 16 m/s from the top of a 65 m cliff. Ignore air resistance and use g = 9.81 m/s². Find the speed v with which it hits the ground.

v₀ = 16 m/sh = 65 mg = 9.81 m/s²

v = m/s

3.Medium

A ball is kicked from level ground at 26 m/s and 40° above the horizontal towards a wall 41 m away. Ignore air resistance and use g = 9.81 m/s². At what height y does the ball pass the wall?

v₀ = 26 m/sθ = 40°x = 41 mg = 9.81 m/s²

y = m

4.Medium

A ball is launched at 45° above horizontal from level ground. Ignore air resistance. Find the horizontal distance x travelled before the ball hits the ground.

v₀ = 26 m/sθ = 45°g = 9.81 m/s²

x = m

5.Hard

A ball is launched at 22 m/s and 25° above the horizontal from the top of a 15 m cliff. Ignore air resistance and use g = 9.81 m/s². Find the greatest height H above the ground at the foot of the cliff.

v₀ = 22 m/sθ = 25°h = 15 mg = 9.81 m/s²

H = m

6.Hard

A ball is launched at 55° above horizontal from the top of a 60 m cliff. Ignore air resistance. Find the horizontal distance x travelled before the ball hits the ground.

v₀ = 18 m/sθ = 55°h = 60 mg = 9.81 m/s²

x = m

Answer key

1. v₀ = 3.296 m/s
2. v = 39.13 m/s
3. y = 13.62 m
4. x = 68.91 m
5. H = 19.41 m
6. x = 54.82 m
