Name: ____________________ Date: ____________

1.Easy

A ball is launched horizontally from the top of a 35 m cliff. Ignore air resistance. Find the horizontal distance x travelled before the ball hits the ground.

v₀ = 24 m/sθ = 0°h = 35 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 = 10 m/sθ = 0°h = 75 mg = 9.81 m/s²

t = s

3.Medium

A ball is kicked from level ground at 40 m/s and 45° above the horizontal towards a wall 49 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 = 45°x = 49 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 = 38 m/sθ = 35°g = 9.81 m/s²

t = s

5.Hard

A ball is launched at 60° above horizontal from the top of a 30 m cliff. Ignore air resistance. Find the horizontal distance x travelled before the ball hits the ground.

v₀ = 27 m/sθ = 60°h = 30 mg = 9.81 m/s²

x = m

6.Hard

A ball is launched at 17 m/s and 55° above the horizontal from the top of a 40 m cliff. Ignore air resistance and use g = 9.81 m/s². Find the greatest height H above the ground at the foot of the cliff.

v₀ = 17 m/sθ = 55°h = 40 mg = 9.81 m/s²

H = m

Answer key

1. x = 64.11 m
2. t = 3.91 s
3. y = 34.28 m
4. t = 4.444 s
5. x = 78.55 m
6. H = 49.88 m
