1.Easy

A ball is launched horizontally from the top of a 70 m cliff. Ignore air resistance. Find the time of flight t until the ball hits the ground.

v₀ = 5 m/sθ = 0°h = 70 mg = 9.81 m/s²

t = s

2.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 = 18 m/sθ = 0°h = 50 mg = 9.81 m/s²

x = m

3.Medium

A ball is kicked from level ground at 26 m/s and 25° above the horizontal towards a wall 16 m away. Ignore air resistance and use g = 9.81 m/s². At what height y does the ball pass the wall?

v₀ = 26 m/sθ = 25°x = 16 mg = 9.81 m/s²

y = m

4.Medium

A ball is launched at 45° above horizontal from level ground. Ignore air resistance. Find the time of flight t until the ball hits the ground.

v₀ = 22 m/sθ = 45°g = 9.81 m/s²

t = s

5.Hard

A ball is launched at 40° above horizontal from the top of a 55 m cliff. Ignore air resistance. Find the horizontal distance x travelled before the ball hits the ground.

v₀ = 34 m/sθ = 40°h = 55 mg = 9.81 m/s²

x = m

6.Hard

A ball is launched at 23 m/s and 20° above the horizontal from the top of a 10 m cliff. Ignore air resistance and use g = 9.81 m/s². Find the speed v with which it hits the ground.

v₀ = 23 m/sθ = 20°h = 10 mg = 9.81 m/s²

v = m/s

Answer key

1. t = 3.778 s
2. x = 57.47 m
3. y = 5.2 m
4. t = 3.172 s
5. x = 162.8 m
6. v = 26.93 m/s
