  1. 1) 5 seconds

    2) No

    Explanation:

    1) When you catch the ball, it returns to its initial height, so the displacement is 0.

    Given:

    Δy = 0 m

    v₀ = 25 m/s

    a = -10 m/s²

    Find: t

    Δy = v₀ t + ½ at²

    0 m = (25 m/s) t + ½ (-10 m/s²) t²

    0 = 25t − 5t²

    0 = 5t (5 − t)

    t = 5

    2) At the maximum height, the vertical velocity is 0 m/s.

    Given:

    v₀ = 215 m/s

    v = 0 m/s

    a = -10 m/s²

    Find: Δy

    v² = v₀² + 2aΔy

    (0 m/s)² = (215 m/s)² + 2 (-10 m/s²) Δy

    Δy ≈ 2310 m

    No, the bullet cannot reach the plane.

  2. technically yes

    Explanation:

    with a gun depending on how fast it shoots so when you fire at something you shoot in front of it a little bit so you hit it but a plane that fast you shoot like 100 feet infront of it...
