1.Easy

A ball is launched horizontally from the top of a 75 m cliff. Ignore air resistance. Find the time of flight t until the ball hits the ground.

v₀ = 13 m/sθ = 0°h = 75 mg = 9.81 m/s²

t = s

2.Easy

A stone is thrown horizontally from the top of a 70 m high wall and lands 47 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 = 47 mg = 9.81 m/s²

v₀ = m/s

3.Medium

A ball is launched at 65° above horizontal from level ground. Ignore air resistance. Find the horizontal distance x travelled before the ball hits the ground.

v₀ = 12 m/sθ = 65°g = 9.81 m/s²

x = m

4.Medium

A ball is launched at 40° above horizontal from level ground. Ignore air resistance. Find the time of flight t until the ball hits the ground.

v₀ = 36 m/sθ = 40°g = 9.81 m/s²

t = s

5.Hard

A ball is thrown from ground level at 34 m/s and 45° 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 = 34 m/sθ = 45°h_roof = 16 mg = 9.81 m/s²

x = m

6.Hard

A ball is launched at 55° above horizontal from the top of a 40 m cliff. Ignore air resistance. Find the time of flight t until the ball hits the ground.

v₀ = 29 m/sθ = 55°h = 40 mg = 9.81 m/s²

t = s

Answer key

1. t = 3.91 s
2. v₀ = 12.44 m/s
3. x = 11.24 m
4. t = 4.718 s
5. x = 98.75 m
6. t = 6.166 s
