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 = 23 m/sθ = 0°h = 15 mg = 9.81 m/s²

t = s

2.Easy

A ball is kicked from level ground at 24 m/s and 50° 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 = 24 m/sθ = 50°g = 9.81 m/s²

t = s

3.Medium

A ball is kicked from level ground at 40 m/s and 50° above the horizontal towards a wall 112 m away. Ignore air resistance and use g = 9.81 m/s². At what height y does the ball pass the wall?

v₀ = 40 m/sθ = 50°x = 112 mg = 9.81 m/s²

y = m

4.Medium

A ball is launched from level ground at 20° above the horizontal and lands 10 m away. Ignore air resistance and use g = 9.81 m/s². Find the launch speed v₀.

θ = 20°R = 10 mg = 9.81 m/s²

v₀ = m/s

5.Hard

A ball is launched at 45° 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 = 26 m/sθ = 45°h = 50 mg = 9.81 m/s²

t = s

6.Hard

A ball is launched at 34 m/s and 20° above the horizontal from the top of a 55 m cliff. Ignore air resistance and use g = 9.81 m/s². Find the speed v with which it hits the ground.

v₀ = 34 m/sθ = 20°h = 55 mg = 9.81 m/s²

v = m/s

Answer key

1. t = 1.749 s
2. t = 1.874 s
3. y = 40.4 m
4. v₀ = 12.35 m/s
5. t = 5.576 s
6. v = 47.28 m/s
