Question

bull's-eye bob at a hunting range fires his rifle at a target 200 meters downrange. the bullet moves horizontally from the rifle barrel with a speed of 400 m/s? how far does the bullet drop from a straight line horizontal path bny the time it reaches the target

Answer 1

Dx = Xo*Tf = 200 m.
400 * Tf = 200
Tf = 0.5 s. = Fall time.

d = 0.5g*Tf^2 = 4.9*0.5^2 = 1.23 m.
