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 = 13 m/sθ = 0°h = 25 mg = 9.81 m/s²

x = m

2.Easy

A ball is kicked from level ground at 40 m/s and 25° 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 = 40 m/sθ = 25°g = 9.81 m/s²

t = s

3.Medium

A ball is launched from level ground at 55° above the horizontal and lands 125 m away. Ignore air resistance and use g = 9.81 m/s². Find the launch speed v₀.

θ = 55°R = 125 mg = 9.81 m/s²

v₀ = m/s

4.Medium

A ball is launched at 45° above horizontal from level ground. Ignore air resistance. Find the horizontal distance x travelled before the ball hits the ground.

v₀ = 24 m/sθ = 45°g = 9.81 m/s²

x = m

5.Hard

A ball is launched at 55° above horizontal from the top of a 25 m cliff. Ignore air resistance. Find the horizontal distance x travelled before the ball hits the ground.

v₀ = 18 m/sθ = 55°h = 25 mg = 9.81 m/s²

x = m

6.Hard

A ball is launched at 20° above horizontal from the top of a 5 m cliff. Ignore air resistance. Find the horizontal distance x travelled before the ball hits the ground.

v₀ = 19 m/sθ = 20°h = 5 mg = 9.81 m/s²

x = m

Answer key

1. x = 29.35 m
2. t = 1.723 s
3. v₀ = 36.12 m/s
4. x = 58.72 m
5. x = 43.52 m
6. x = 33.39 m
