The arrow was fired upward with an initial velocity of 50 m / s. How long did it take for the arrow to rise and how long did the flight last?
Task data: V0 (speed of the taken boom during launch, initial speed) = 50 m / s.
Reference values: g (acceleration due to gravity) ≈ 10 m / s2.
1) Duration of lifting the taken boom: t1 = (V1 – V0) / a = -V0 / (-g) = 50/10 = 5 s.
2) Total flight duration: t = t1 + t2 = 2t1 = 2 * 5 = 10 s.
Answer: The taken arrow went up for 5 seconds; the flight lasted 10 seconds.
