A. What was the bullet's fight time?
B. What was the bullet's speed as it left the barrel?

  • Physics:Projectile Motion - ,

    see above.

  • Physics:Projectile Motion - ,

    To get the time use this:
    T=(sqrt)of (2(.027m)/g
    Now initial velocity formula:
    V=d/t
    V=52/.074=700.51-701m/s

  • Physics:Projectile Motion - ,

    700

  • Physics:Projectile Motion - ,

    wrong
