1.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 = 25 m/sθ = 0°h = 10 mg = 9.81 m/s²

x = m

2.Easy

A stone is thrown horizontally from the top of a 60 m high wall and lands 45 m from the foot of the wall. Ignore air resistance and use g = 9.81 m/s². Find the launch speed v₀.

h = 60 mx = 45 mg = 9.81 m/s²

v₀ = m/s

3.Medium

A ball is launched from level ground at 25° above the horizontal and lands 10 m away. Ignore air resistance and use g = 9.81 m/s². Find the launch speed v₀.

θ = 25°R = 10 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 horizontal distance x travelled before the ball hits the ground.

v₀ = 10 m/sθ = 30°g = 9.81 m/s²

x = m

5.Hard

A ball is launched at 25° above horizontal from the top of a 60 m cliff. Ignore air resistance. Find the time of flight t until the ball hits the ground.

v₀ = 34 m/sθ = 25°h = 60 mg = 9.81 m/s²

t = s

6.Hard

A ball is launched at 40° above horizontal from the top of a 35 m cliff. Ignore air resistance. Find the horizontal distance x travelled before the ball hits the ground.

v₀ = 10 m/sθ = 40°h = 35 mg = 9.81 m/s²

x = m

Answer key

1. x = 35.7 m
2. v₀ = 12.87 m/s
3. v₀ = 11.32 m/s
4. x = 8.828 m
5. t = 5.257 s
6. x = 26.09 m
