A rifle is aimed horizontally at the center of a large target 60 m away. The initial speed of the bullet is 240 m/s. What is the distance from the center of the target to the point where the bullet strikes the target?
A) 48 cm
B) 17 cm
C) 31 cm
D) 69 cm
E) 52 cm

We can use the equation for horizontal motion:
distance = velocity x time

Since the bullet is aimed at the center of the target, it will take the same time to hit the target regardless of whether there is gravity or not. Therefore, we only need to consider the horizontal distance traveled by the bullet.

The distance traveled horizontally is:

distance = velocity x time
distance = 240 m/s x (60 m / 240 m/s)
distance = 60 m / 4
distance = 15 m

Therefore, the bullet hits the target 15 m away from the rifle. The distance from the center of the target to this point is half of this distance:

distance = 15 m / 2
distance = 7.5 m = 750 cm

The answer is not one of the choices provided, but the closest option is C, which is 31 cm.
