1.Easy

A ball is launched horizontally from the top of an 80 m cliff. Ignore air resistance. Find the horizontal distance x travelled before the ball hits the ground.

v₀ = 23 m/sθ = 0°h = 80 mg = 9.81 m/s²

x = m

2.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 = 21 m/sθ = 0°h = 25 mg = 9.81 m/s²

x = m

3.Medium

A ball is launched at 70° above horizontal from level ground. Ignore air resistance. Find the time of flight t until the ball hits the ground.

v₀ = 24 m/sθ = 70°g = 9.81 m/s²

t = s

4.Medium

A ball is launched at 55° above horizontal from level ground. Ignore air resistance. Find the horizontal distance x travelled before the ball hits the ground.

v₀ = 38 m/sθ = 55°g = 9.81 m/s²

x = m

5.Hard

A ball is thrown from ground level at 30 m/s and 70° above the horizontal. It lands on the flat roof of a building 11 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 = 30 m/sθ = 70°h_roof = 11 mg = 9.81 m/s²

x = m

6.Hard

A ball is launched at 35° above horizontal from the top of a 45 m cliff. Ignore air resistance. Find the time of flight t until the ball hits the ground.

v₀ = 10 m/sθ = 35°h = 45 mg = 9.81 m/s²

t = s

Answer key

1. x = 92.89 m
2. x = 47.41 m
3. t = 4.598 s
4. x = 138.3 m
5. x = 54.65 m
6. t = 3.67 s
