1.Easy

A ball is launched horizontally from the top of a 45 m cliff. Ignore air resistance. Find the horizontal distance x travelled before the ball hits the ground.

v₀ = 21 m/sθ = 0°h = 45 mg = 9.81 m/s²

x = m

2.Easy

A ball is launched horizontally from the top of an 80 m cliff. Ignore air resistance. Find the horizontal distance x travelled before the ball hits the ground.

v₀ = 21 m/sθ = 0°h = 80 mg = 9.81 m/s²

x = m

3.Medium

A ball is kicked from level ground at 34 m/s and 20° above the horizontal towards a wall 61 m away. Ignore air resistance and use g = 9.81 m/s². At what height y does the ball pass the wall?

v₀ = 34 m/sθ = 20°x = 61 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 maximum height H the ball reaches.

v₀ = 18 m/sθ = 35°g = 9.81 m/s²

H = m

5.Hard

A ball is launched at 45° above horizontal from the top of a 60 m cliff. Ignore air resistance. Find the time of flight t until the ball hits the ground.

v₀ = 25 m/sθ = 45°h = 60 mg = 9.81 m/s²

t = s

6.Hard

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

v₀ = 27 m/sθ = 25°h = 25 mg = 9.81 m/s²

t = s

Answer key

1. x = 63.61 m
2. x = 84.81 m
3. y = 4.322 m
4. H = 5.433 m
5. t = 5.736 s
6. t = 3.703 s
