Problem
At a shooting gallery, a man fires a bullet from a rifle horizontally at a target.
The target is 75.00 m away.
The bullet leaves the rifle at a speed of 150.0 ms−1 .
Ignoring any effects of air friction on the bullet, and using g=10 ms−2 :
(1) calculate the time it takes for the bullet to hit the target,
(2) using the equation v2=u2+2as , with the appropriate value for v , show that the bullet hits the target 1.25 m below the horizontal,
(3) calculate the total velocity vector for the bullet just as it hits the target.
