1.Easy

A ball is thrown horizontally at 10 m/s from the top of an 80 m cliff. Ignore air resistance and use g = 9.81 m/s². Find the speed v with which it hits the ground.

v₀ = 10 m/sh = 80 mg = 9.81 m/s²

v = m/s

2.Easy

A stone is thrown horizontally from the top of a 35 m high wall and lands 30 m from the foot of the wall. Ignore air resistance and use g = 9.81 m/s². Find the launch speed v₀.

h = 35 mx = 30 mg = 9.81 m/s²

v₀ = m/s

3.Medium

A ball is launched at 60° above horizontal from level ground. Ignore air resistance. Find the time of flight t until the ball hits the ground.

v₀ = 30 m/sθ = 60°g = 9.81 m/s²

t = s

4.Medium

A ball is launched at 20° above horizontal from level ground. Ignore air resistance. Find the horizontal distance x travelled before the ball hits the ground.

v₀ = 28 m/sθ = 20°g = 9.81 m/s²

x = m

5.Hard

A ball is launched at 50° above horizontal from the top of a 10 m cliff. Ignore air resistance. Find the horizontal distance x travelled before the ball hits the ground.

v₀ = 25 m/sθ = 50°h = 10 mg = 9.81 m/s²

x = m

6.Hard

A ball is launched at 55° 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 = 20 m/sθ = 55°h = 55 mg = 9.81 m/s²

t = s

Answer key

1. v = 40.86 m/s
2. v₀ = 11.23 m/s
3. t = 5.297 s
4. x = 51.37 m
5. x = 70.24 m
6. t = 5.412 s
