1.Easy

A ball is launched horizontally from the top of a 25 m cliff. Ignore air resistance. Find the horizontal distance x travelled before the ball hits the ground.

v₀ = 5 m/sθ = 0°h = 25 mg = 9.81 m/s²

x = m

2.Easy

A ball is launched horizontally from the top of a 45 m cliff. Ignore air resistance. Find the horizontal distance x travelled before the ball hits the ground.

v₀ = 6 m/sθ = 0°h = 45 mg = 9.81 m/s²

x = m

3.Medium

A ball is launched at 20° above horizontal from level ground. Ignore air resistance. Find the horizontal distance x travelled before the ball hits the ground.

v₀ = 28 m/sθ = 20°g = 9.81 m/s²

x = m

4.Medium

A ball is launched at 60° above horizontal from level ground. Ignore air resistance. Find the time of flight t until the ball hits the ground.

v₀ = 36 m/sθ = 60°g = 9.81 m/s²

t = s

5.Hard

A ball is launched at 12 m/s and 60° above the horizontal from the top of a 35 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 = 12 m/sθ = 60°h = 35 mg = 9.81 m/s²

H = m

6.Hard

A ball is launched at 45° above horizontal from the top of a 60 m cliff. Ignore air resistance. Find the time of flight t until the ball hits the ground.

v₀ = 18 m/sθ = 45°h = 60 mg = 9.81 m/s²

t = s

Answer key

1. x = 11.29 m
2. x = 18.17 m
3. x = 51.37 m
4. t = 6.356 s
5. H = 40.5 m
6. t = 5.028 s
