1.Easy

A stone is thrown horizontally from the top of a 45 m high wall and lands 43 m from the foot of the wall. Ignore air resistance and use g = 9.81 m/s². Find the launch speed v₀.

h = 45 mx = 43 mg = 9.81 m/s²

v₀ = m/s

2.Easy

A ball is launched horizontally from the top of a 5 m cliff. Ignore air resistance. Find the horizontal distance x travelled before the ball hits the ground.

v₀ = 25 m/sθ = 0°h = 5 mg = 9.81 m/s²

x = m

3.Medium

A ball is launched at 40° above horizontal from level ground. Ignore air resistance. Find the maximum height H the ball reaches.

v₀ = 40 m/sθ = 40°g = 9.81 m/s²

H = m

4.Medium

A ball is launched at 50° above horizontal from level ground. Ignore air resistance. Find the horizontal distance x travelled before the ball hits the ground.

v₀ = 14 m/sθ = 50°g = 9.81 m/s²

x = m

5.Hard

A ball is thrown from ground level at 35 m/s and 50° above the horizontal. It lands on the flat roof of a building 14 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 = 35 m/sθ = 50°h_roof = 14 mg = 9.81 m/s²

x = m

6.Hard

A ball is launched at 25° above horizontal from the top of a 40 m cliff. Ignore air resistance. Find the time of flight t until the ball hits the ground.

v₀ = 16 m/sθ = 25°h = 40 mg = 9.81 m/s²

t = s

Answer key

1. v₀ = 14.2 m/s
2. x = 25.24 m
3. H = 33.69 m
4. x = 19.68 m
5. x = 109.8 m
6. t = 3.627 s
