1.Easy

A stone is thrown horizontally from the top of a 70 m high wall and lands 57 m from the foot of the wall. Ignore air resistance and use g = 9.81 m/s². Find the launch speed v₀.

h = 70 mx = 57 mg = 9.81 m/s²

v₀ = m/s

2.Easy

A ball is kicked from level ground at 40 m/s and 60° 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 = 40 m/sθ = 60°g = 9.81 m/s²

t = s

3.Medium

A ball is launched at 30° above horizontal from level ground. Ignore air resistance. Find the horizontal distance x travelled before the ball hits the ground.

v₀ = 20 m/sθ = 30°g = 9.81 m/s²

x = m

4.Medium

A ball is launched from level ground at 12 m/s and must land 5 m away. Ignore air resistance and use g = 9.81 m/s². Find the smaller of the two possible launch angles θ.

v₀ = 12 m/sR = 5 mg = 9.81 m/s²

θ = °

5.Hard

A ball is launched at 35° above horizontal from the top of a 55 m cliff. Ignore air resistance. Find the time of flight t until the ball hits the ground.

v₀ = 22 m/sθ = 35°h = 55 mg = 9.81 m/s²

t = s

6.Hard

A ball is launched at 32 m/s and 35° above the horizontal from the top of a 15 m cliff. Ignore air resistance and use g = 9.81 m/s². Find the speed v with which it hits the ground.

v₀ = 32 m/sθ = 35°h = 15 mg = 9.81 m/s²

v = m/s

Answer key

1. v₀ = 15.09 m/s
2. t = 3.531 s
3. x = 35.31 m
4. θ = 9.957 °
5. t = 4.873 s
6. v = 36.31 m/s
