Question
A bullet is aimed at a target on the wall a distance "L" awayfrom the firing position. Because of gravity, the strikes the wallat a distance ?y.
If the distance L was half as large and the bullet had thesame initial velocity, how would ?y be affected?
A. ?y will double
B. ?y will be half as large
C. ?y will be four time larger
D. ?y will be one fourth as large
E.

A. ?y will double
B. ?y will be half as large
C. ?y will be four time larger
D. ?y will be one fourth as large
E. ?y is not possible to determine unless numerical values are given for the distances
Explanation / Answer
the time it takes to hit the wall is distance/velocity, or L/V now if L were cut in half, then time would be cut in half. so plug into a kinematic x=xi + vt + .5at^2 *vertical, so no v initial x=.5at^2 Now if L were in half, x=(.5)(a)(1/4t^2) So D, 1/4 as large
