1.Easy

A ball is launched horizontally from the top of a 65 m cliff. Ignore air resistance. Find the horizontal distance x travelled before the ball hits the ground.

v₀ = 20 m/sθ = 0°h = 65 mg = 9.81 m/s²

x = m

2.Easy

A ball is launched horizontally from the top of a 10 m cliff. Ignore air resistance. Find the horizontal distance x travelled before the ball hits the ground.

v₀ = 10 m/sθ = 0°h = 10 mg = 9.81 m/s²

x = m

3.Medium

A ball is launched from level ground at 25° above the horizontal and lands 120 m away. Ignore air resistance and use g = 9.81 m/s². Find the launch speed v₀.

θ = 25°R = 120 mg = 9.81 m/s²

v₀ = m/s

4.Medium

A ball is launched at 40° above horizontal from level ground. Ignore air resistance. Find the horizontal distance x travelled before the ball hits the ground.

v₀ = 18 m/sθ = 40°g = 9.81 m/s²

x = m

5.Hard

A ball is launched at 60° above horizontal from the top of a 15 m cliff. Ignore air resistance. Find the time of flight t until the ball hits the ground.

v₀ = 28 m/sθ = 60°h = 15 mg = 9.81 m/s²

t = s

6.Hard

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

v₀ = 12 m/sθ = 25°h = 55 mg = 9.81 m/s²

x = m

Answer key

1. x = 72.81 m
2. x = 14.28 m
3. v₀ = 39.2 m/s
4. x = 32.53 m
5. t = 5.5 s
6. x = 42.47 m
