1.Easy

A ball is launched horizontally from the top of a 60 m cliff. Ignore air resistance. Find the horizontal distance x travelled before the ball hits the ground.

v₀ = 5 m/sθ = 0°h = 60 mg = 9.81 m/s²

x = m

2.Easy

A ball is launched horizontally from the top of a 75 m cliff. Ignore air resistance. Find the time of flight t until the ball hits the ground.

v₀ = 12 m/sθ = 0°h = 75 mg = 9.81 m/s²

t = s

3.Medium

A ball is kicked from level ground at 36 m/s and 55° above the horizontal towards a wall 87 m away. Ignore air resistance and use g = 9.81 m/s². At what height y does the ball pass the wall?

v₀ = 36 m/sθ = 55°x = 87 mg = 9.81 m/s²

y = m

4.Medium

A ball is launched at 35° above horizontal from level ground. Ignore air resistance. Find the time of flight t until the ball hits the ground.

v₀ = 12 m/sθ = 35°g = 9.81 m/s²

t = s

5.Hard

A ball is launched at 15° above horizontal from the top of a 20 m cliff. Ignore air resistance. Find the horizontal distance x travelled before the ball hits the ground.

v₀ = 31 m/sθ = 15°h = 20 mg = 9.81 m/s²

x = m

6.Hard

A ball is launched at 25° above horizontal from the top of a 35 m cliff. Ignore air resistance. Find the time of flight t until the ball hits the ground.

v₀ = 29 m/sθ = 25°h = 35 mg = 9.81 m/s²

t = s

Answer key

1. x = 17.49 m
2. t = 3.91 s
3. y = 37.17 m
4. t = 1.403 s
5. x = 89.73 m
6. t = 4.198 s
