Question

Suppose a rifle fires a bullet horizontally 100 meters from a target, and the bullet drops into the
target 8.5 cm below the center cross hair. Use the system of equations presented to determine the
muzzle velocity of the rifle.

These are sll of the equations I have and I am not sure which one to use. I am very confused on this problem as well in general. Can you walk me through your work? Any help is appreciated!

  • x = v0xt
  • vx = v0x
  • y = v0yt + ½ gt2
  • vy = v0y + g
  • y = v0yt + ½ gt^2
  • h = ½ gt^2
  • t = √ (2h/g)
  • x = v0xt
  • vx = R/t
  • vx = R/ √ (2h/g)
  • vx = R √ (g/2h)
