Name: ____________________ Date: ____________

1.Easy

A ball is kicked from level ground at 24 m/s and 65° 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 = 24 m/sθ = 65°g = 9.81 m/s²

t = s

2.Easy

A ball is kicked from level ground at 16 m/s and 65° 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 = 16 m/sθ = 65°g = 9.81 m/s²

t = s

3.Medium

A ball is launched at 45° above horizontal from level ground. Ignore air resistance. Find the maximum height H the ball reaches.

v₀ = 40 m/sθ = 45°g = 9.81 m/s²

H = m

4.Medium

A ball is launched from level ground at 30° above the horizontal and lands 30 m away. Ignore air resistance and use g = 9.81 m/s². Find the launch speed v₀.

θ = 30°R = 30 mg = 9.81 m/s²

v₀ = m/s

5.Hard

A ball is launched at 15° above horizontal from the top of a 25 m cliff. Ignore air resistance. Find the horizontal distance x travelled before the ball hits the ground.

v₀ = 26 m/sθ = 15°h = 25 mg = 9.81 m/s²

x = m

6.Hard

A ball is thrown from ground level at 29 m/s and 60° above the horizontal. It lands on the flat roof of a building 3 m high, on its way down. Ignore air resistance and use g = 9.81 m/s². Find the horizontal distance x from the launch point to where it lands.

v₀ = 29 m/sθ = 60°h_roof = 3 mg = 9.81 m/s²

x = m

Answer key

1. t = 2.217 s
2. t = 1.478 s
3. H = 40.77 m
4. v₀ = 18.43 m/s
5. x = 76.48 m
6. x = 72.47 m
