1.Easy

A ball is launched horizontally from the top of a 70 m cliff. Ignore air resistance. Find the horizontal distance x travelled before the ball hits the ground.

v₀ = 13 m/sθ = 0°h = 70 mg = 9.81 m/s²

x = m

2.Easy

A stone is thrown horizontally from the top of a 60 m high wall and lands 17 m from the foot of the wall. Ignore air resistance and use g = 9.81 m/s². Find the launch speed v₀.

h = 60 mx = 17 mg = 9.81 m/s²

v₀ = m/s

3.Medium

A ball is launched at 35° above horizontal from level ground. Ignore air resistance. Find the maximum height H the ball reaches.

v₀ = 16 m/sθ = 35°g = 9.81 m/s²

H = m

4.Medium

A ball is launched at 60° above horizontal from level ground. Ignore air resistance. Find the maximum height H the ball reaches.

v₀ = 40 m/sθ = 60°g = 9.81 m/s²

H = m

5.Hard

A ball is thrown from ground level at 25 m/s and 50° above the horizontal. It lands on the flat roof of a building 7 m high, on its way down. Ignore air resistance and use g = 9.81 m/s². Find the horizontal distance x from the launch point to where it lands.

v₀ = 25 m/sθ = 50°h_roof = 7 mg = 9.81 m/s²

x = m

6.Hard

A ball is launched at 20° above horizontal from the top of a 50 m cliff. Ignore air resistance. Find the time of flight t until the ball hits the ground.

v₀ = 12 m/sθ = 20°h = 50 mg = 9.81 m/s²

t = s

Answer key

1. x = 49.11 m
2. v₀ = 4.861 m/s
3. H = 4.293 m
4. H = 61.16 m
5. x = 56.18 m
6. t = 3.638 s
