1.Easy

A ball is kicked from level ground at 36 m/s and 40° 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 = 36 m/sθ = 40°g = 9.81 m/s²

t = s

2.Easy

A ball is launched horizontally from the top of an 80 m cliff. Ignore air resistance. Find the time of flight t until the ball hits the ground.

v₀ = 7 m/sθ = 0°h = 80 mg = 9.81 m/s²

t = s

3.Medium

A ball is launched from level ground at 25° above the horizontal and lands 75 m away. Ignore air resistance and use g = 9.81 m/s². Find the launch speed v₀.

θ = 25°R = 75 mg = 9.81 m/s²

v₀ = m/s

4.Medium

A ball is launched from level ground at 38 m/s and must land 100 m away. Ignore air resistance and use g = 9.81 m/s². Find the smaller of the two possible launch angles θ.

v₀ = 38 m/sR = 100 mg = 9.81 m/s²

θ = °

5.Hard

A ball is launched at 34 m/s and 55° above the horizontal from the top of a 15 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 = 34 m/sθ = 55°h = 15 mg = 9.81 m/s²

α = °

6.Hard

A ball is launched at 35° above horizontal from the top of a 50 m cliff. Ignore air resistance. Find the time of flight t until the ball hits the ground.

v₀ = 16 m/sθ = 35°h = 50 mg = 9.81 m/s²

t = s

Answer key

1. t = 2.359 s
2. t = 4.039 s
3. v₀ = 30.99 m/s
4. θ = 21.4 °
5. α = 59.2 °
6. t = 4.262 s
