Asked by Jacob
A dart gun is aimed horizontally at the center of a large target 150 m away. The initial velocity of the dart is 450 m/s. (Ignore air resistance)
a) Where does the dart strike the target (relative to the center of the target)?
b) To hit the center of the target the dart must be aimed at a point above the center of the target. Find the angle of elevation needed to hit the target.

a. d = Xo*Tf = 150 m.
450 * Tf = 150
Tf = 0.333 s.
d = 0.5g*Tf^2 = 4.9*0.333^2 = 0.544 m.
