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 = 21 m/sθ = 0°h = 25 mg = 9.81 m/s²

x = m

2.Easy

A ball is kicked from level ground at 22 m/s and 30° 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 = 22 m/sθ = 30°g = 9.81 m/s²

t = s

3.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 = 22 m/sθ = 50°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 time of flight t until the ball hits the ground.

v₀ = 22 m/sθ = 55°g = 9.81 m/s²

t = s

5.Hard

A ball is launched at 24 m/s and 55° above the horizontal from the top of a 25 m cliff. Ignore air resistance and use g = 9.81 m/s². Find the speed v with which it hits the ground.

v₀ = 24 m/sθ = 55°h = 25 mg = 9.81 m/s²

v = m/s

6.Hard

A ball is launched at 55° above horizontal from the top of a 20 m cliff. Ignore air resistance. Find the horizontal distance x travelled before the ball hits the ground.

v₀ = 29 m/sθ = 55°h = 20 mg = 9.81 m/s²

x = m

Answer key

1. x = 47.41 m
2. t = 1.121 s
3. x = 48.59 m
4. t = 3.674 s
5. v = 32.66 m/s
6. x = 92.73 m
