Question

 A parkour artist jumps from one rooftop to another. He jumps off the first rooftop with a velocity of 5m/s, angled at 30° to the horizontal. He stays airborne for 0.70 seconds before landing on the second rooftop.

a. What horizontal distance (𝑥⃗2) did the parkour artist travel?

Answer 1

The horizontal distance is

$$x=v_xt=v\cos\theta·t=5\cos30°·0.7,\\ x=3.03\text{ m}.$$
