1.Easy

A ball is launched horizontally from the top of a 15 m cliff. Ignore air resistance. Find the time of flight t until the ball hits the ground.

v₀ = 21 m/sθ = 0°h = 15 mg = 9.81 m/s²

t = s

2.Easy

A stone is thrown horizontally from the top of an 80 m high wall and lands 19 m from the foot of the wall. Ignore air resistance and use g = 9.81 m/s². Find the launch speed v₀.

h = 80 mx = 19 mg = 9.81 m/s²

v₀ = m/s

3.Medium

A ball is launched from level ground at 75° above the horizontal and lands 110 m away. Ignore air resistance and use g = 9.81 m/s². Find the launch speed v₀.

θ = 75°R = 110 mg = 9.81 m/s²

v₀ = m/s

4.Medium

A ball is launched from level ground at 35° above the horizontal and lands 125 m away. Ignore air resistance and use g = 9.81 m/s². Find the launch speed v₀.

θ = 35°R = 125 mg = 9.81 m/s²

v₀ = m/s

5.Hard

A ball is launched at 15 m/s and 55° above the horizontal from the top of a 20 m cliff. Ignore air resistance and use g = 9.81 m/s². At what angle α below the horizontal does it hit the ground?

v₀ = 15 m/sθ = 55°h = 20 mg = 9.81 m/s²

α = °

6.Hard

A ball is launched at 16 m/s and 45° above the horizontal from the top of a 15 m cliff. Ignore air resistance and use g = 9.81 m/s². Find the greatest height H above the ground at the foot of the cliff.

v₀ = 16 m/sθ = 45°h = 15 mg = 9.81 m/s²

H = m

Answer key

1. t = 1.749 s
2. v₀ = 4.705 m/s
3. v₀ = 46.46 m/s
4. v₀ = 36.12 m/s
5. α = 69.74 °
6. H = 21.52 m
