1.Easy

A ball is thrown horizontally at 17 m/s from the top of a 75 m cliff. Ignore air resistance and use g = 9.81 m/s². Find the speed v with which it hits the ground.

v₀ = 17 m/sh = 75 mg = 9.81 m/s²

v = m/s

2.Easy

A ball is launched horizontally from the top of a 50 m cliff. Ignore air resistance. Find the time of flight t until the ball hits the ground.

v₀ = 6 m/sθ = 0°h = 50 mg = 9.81 m/s²

t = s

3.Medium

A ball is launched from level ground at 20 m/s and must land 25 m away. Ignore air resistance and use g = 9.81 m/s². Find the smaller of the two possible launch angles θ.

v₀ = 20 m/sR = 25 mg = 9.81 m/s²

θ = °

4.Medium

A ball is launched at 70° above horizontal from level ground. Ignore air resistance. Find the horizontal distance x travelled before the ball hits the ground.

v₀ = 12 m/sθ = 70°g = 9.81 m/s²

x = m

5.Hard

A ball is launched at 40° above horizontal from the top of a 25 m cliff. Ignore air resistance. Find the time of flight t until the ball hits the ground.

v₀ = 34 m/sθ = 40°h = 25 mg = 9.81 m/s²

t = s

6.Hard

A ball is launched at 45° above horizontal from the top of a 15 m cliff. Ignore air resistance. Find the horizontal distance x travelled before the ball hits the ground.

v₀ = 24 m/sθ = 45°h = 15 mg = 9.81 m/s²

x = m

Answer key

1. v = 41.96 m/s
2. t = 3.193 s
3. θ = 18.91 °
4. x = 9.435 m
5. t = 5.4 s
6. x = 71.1 m
