The time for projectile motion is completely determined by the vertical motion. So any projectile that has an initial vertical velocity of 14.3 m / s 14.3 m / s and lands 20.0 m below its starting altitude will spend 3.96 s in the air.
The time a projectile is in the air is governed by its vertical motion alone. Thus, we solve for t first. While the ball is rising and falling vertically, the horizontal motion continues at a constant velocity.
26 maj 2019 · The vertical component of velocity undergoes an acceleration of $g$ downwards whereas the horizontal component of velocity is constant. The distance traveled horizontally by the projectile depends on the horizontal speed of the projectile and the time that the projectile is in the air (time of flight).
The vertical velocity changes by -9.8 m/s each second of motion. On the other hand, the horizontal acceleration is 0 m/s/s and the projectile continues with a constant horizontal velocity throughout its entire trajectory.
11 sie 2021 · As mentioned earlier, the time for projectile motion is determined completely by the vertical motion. Thus, any projectile that has an initial vertical velocity of 21.2 m/s and lands 10.0 m above its starting altitude spends 3.79 s in the air. The negative angle means the velocity is 53.1° below the horizontal at the point of impact.
The horizontal velocity remains constant, but the vertical velocity varies linearly, because the acceleration is constant. At any time, \(\mathrm{t}\), the velocity is: \[\begin{align} \mathrm{u_x} & \mathrm{=u⋅ \cos θ} \\ \mathrm{u_y} & \mathrm{=u⋅ \sin θ−g⋅t} \end{align}\]
