1.Easy

A stone is thrown horizontally from the top of a 15 m high wall and lands 16 m from the foot of the wall. Ignore air resistance and use g = 9.81 m/s². Find the launch speed v₀.

h = 15 mx = 16 mg = 9.81 m/s²

v₀ = m/s

2.Easy

A ball is thrown horizontally at 24 m/s from the top of a 35 m cliff. Ignore air resistance and use g = 9.81 m/s². Find the speed v with which it hits the ground.

v₀ = 24 m/sh = 35 mg = 9.81 m/s²

v = m/s

3.Medium

A ball is launched from level ground at 32 m/s and must land 80 m away. Ignore air resistance and use g = 9.81 m/s². Find the smaller of the two possible launch angles θ.

v₀ = 32 m/sR = 80 mg = 9.81 m/s²

θ = °

4.Medium

A ball is launched at 45° above horizontal from level ground. Ignore air resistance. Find the horizontal distance x travelled before the ball hits the ground.

v₀ = 12 m/sθ = 45°g = 9.81 m/s²

x = m

5.Hard

A ball is launched at 40° above horizontal from the top of a 50 m cliff. Ignore air resistance. Find the time of flight t until the ball hits the ground.

v₀ = 18 m/sθ = 40°h = 50 mg = 9.81 m/s²

t = s

6.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 = 31 m/sθ = 45°h = 60 mg = 9.81 m/s²

t = s

Answer key

1. v₀ = 9.149 m/s
2. v = 35.53 m/s
3. θ = 25.02 °
4. x = 14.68 m
5. t = 4.583 s
6. t = 6.385 s
