Name: ____________________ Date: ____________

1.Easy

A ball is launched horizontally from the top of a 50 m cliff. Ignore air resistance. Find the horizontal distance x travelled before the ball hits the ground.

v₀ = 10 m/sθ = 0°h = 50 mg = 9.81 m/s²

x = m

2.Easy

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

v₀ = 16 m/sθ = 0°h = 20 mg = 9.81 m/s²

x = m

3.Medium

A ball is launched from level ground at 25° above the horizontal and lands 70 m away. Ignore air resistance and use g = 9.81 m/s². Find the launch speed v₀.

θ = 25°R = 70 mg = 9.81 m/s²

v₀ = m/s

4.Medium

A ball is launched at 30° above horizontal from level ground. Ignore air resistance. Find the maximum height H the ball reaches.

v₀ = 24 m/sθ = 30°g = 9.81 m/s²

H = m

5.Hard

A ball is launched at 60° above horizontal from the top of a 5 m cliff. Ignore air resistance. Find the time of flight t until the ball hits the ground.

v₀ = 20 m/sθ = 60°h = 5 mg = 9.81 m/s²

t = s

6.Hard

A ball is launched at 17 m/s and 25° 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 = 17 m/sθ = 25°h = 25 mg = 9.81 m/s²

v = m/s

Answer key

1. x = 31.93 m
2. x = 32.31 m
3. v₀ = 29.94 m/s
4. H = 7.339 m
5. t = 3.799 s
6. v = 27.92 m/s
