將物理題目翻譯成中文~~

48.A projectile of mass 0.75 kg is shot straight up with an initial speed of 18 m/s. (a) How high would it go if there were no air friction? (b) If the projectile rises to a maximum height of only 11.8 m, determine the magnitude of the average force due to air resistance.

Update:

請勿使用翻譯軟體~~3Q!!!

    A projectile of mass 0.75 kg is shot straight up with an initial speed of 18 m/s.

    一個發射體質量重0.75公斤,以初速18公尺/秒筆直射出,試問:

    (a) How high would it go if there were no air friction?

    (a)如果沒有空氣摩擦力,該發射體會飛多高?

    (b) If the projectile rises to a maximum height of only 11.8 m, determine the magnitude of the average force due to air resistance.

    (b)如果發射體上升最高僅有11.8公尺,則因空氣阻力所產生的平均力量有多少?

    48.A 大量子彈頭0.75 公斤被射擊直接以18 m/s 的最初的速度。(a) 它多麼高會去如果沒有空氣摩擦? (b) 如果子彈頭上升到最大高度僅僅11.8 m, 確定平均力量的巨大由於空氣抵抗。
