1.Easy

A ball is launched horizontally from the top of a 60 m cliff. Ignore air resistance. Find the horizontal distance x travelled before the ball hits the ground.

v₀ = 5 m/sθ = 0°h = 60 mg = 9.81 m/s²

x = m

2.Easy

A ball is thrown horizontally at 25 m/s from the top of a 60 m cliff. Ignore air resistance and use g = 9.81 m/s². Find the speed v with which it hits the ground.

v₀ = 25 m/sh = 60 mg = 9.81 m/s²

v = m/s

3.Medium

A ball is kicked from level ground at 14 m/s and 60° above the horizontal towards a wall 10 m away. Ignore air resistance and use g = 9.81 m/s². At what height y does the ball pass the wall?

v₀ = 14 m/sθ = 60°x = 10 mg = 9.81 m/s²

y = m

4.Medium

A ball is launched at 50° above horizontal from level ground. Ignore air resistance. Find the time of flight t until the ball hits the ground.

v₀ = 16 m/sθ = 50°g = 9.81 m/s²

t = s

5.Hard

A ball is thrown from ground level at 35 m/s and 60° above the horizontal. It lands on the flat roof of a building 16 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 = 35 m/sθ = 60°h_roof = 16 mg = 9.81 m/s²

x = m

6.Hard

A ball is launched at 30° above horizontal from the top of a 10 m cliff. Ignore air resistance. Find the time of flight t until the ball hits the ground.

v₀ = 27 m/sθ = 30°h = 10 mg = 9.81 m/s²

t = s

Answer key

1. x = 17.49 m
2. v = 42.45 m/s
3. y = 7.31 m
4. t = 2.499 s
5. x = 97.94 m
6. t = 3.359 s
