1.Easy

A ball is launched horizontally from the top of a 35 m cliff. Ignore air resistance. Find the horizontal distance x travelled before the ball hits the ground.

v₀ = 7 m/sθ = 0°h = 35 mg = 9.81 m/s²

x = m

2.Easy

A ball is kicked from level ground at 28 m/s and 60° above the horizontal. Ignore air resistance and use g = 9.81 m/s². How long t after the kick does it reach its highest point?

v₀ = 28 m/sθ = 60°g = 9.81 m/s²

t = s

3.Medium

A ball is launched at 65° above horizontal from level ground. Ignore air resistance. Find the horizontal distance x travelled before the ball hits the ground.

v₀ = 10 m/sθ = 65°g = 9.81 m/s²

x = m

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 = 24 m/sθ = 55°g = 9.81 m/s²

x = m

5.Hard

A ball is launched at 45° 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 = 20 m/sθ = 45°h = 60 mg = 9.81 m/s²

x = m

6.Hard

A ball is thrown from ground level at 27 m/s and 30° above the horizontal. It lands on the flat roof of a building 4 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 = 27 m/sθ = 30°h_roof = 4 mg = 9.81 m/s²

x = m

Answer key

1. x = 18.7 m
2. t = 2.472 s
3. x = 7.809 m
4. x = 55.17 m
5. x = 73.89 m
6. x = 56.46 m
