1.Easy

A ball is kicked from level ground at 30 m/s and 25° 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 = 30 m/sθ = 25°g = 9.81 m/s²

t = s

2.Easy

A ball is kicked from level ground at 30 m/s and 35° 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 = 30 m/sθ = 35°g = 9.81 m/s²

t = s

3.Medium

A ball is launched at 35° above horizontal from level ground. Ignore air resistance. Find the horizontal distance x travelled before the ball hits the ground.

v₀ = 20 m/sθ = 35°g = 9.81 m/s²

x = m

4.Medium

A ball is launched from level ground at 45° above the horizontal and lands 35 m away. Ignore air resistance and use g = 9.81 m/s². Find the launch speed v₀.

θ = 45°R = 35 mg = 9.81 m/s²

v₀ = m/s

5.Hard

A ball is launched at 35° 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 = 25 m/sθ = 35°h = 20 mg = 9.81 m/s²

x = m

6.Hard

A ball is launched at 19 m/s and 40° above the horizontal from the top of a 25 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 = 19 m/sθ = 40°h = 25 mg = 9.81 m/s²

H = m

Answer key

1. t = 1.292 s
2. t = 1.754 s
3. x = 38.32 m
4. v₀ = 18.53 m/s
5. x = 80.98 m
6. H = 32.6 m
