Question

A rifle is aimed horizontally at a target 51.0 m away. The bullet hits the target 1.60 cm below the aim point. What was the bullet's speed as it left the barrel?

Step 1

Given Information :

Target distance is S_{x} = 51 m

Bullet hits the target 1.6 cm bellow the aim point.

S_{y} = 1.6 cm = 0.016 m

Motion of the bullet is as shown in the figure below.

Step 2

We can find the time taken by the bullet to travel 0.016 m in vertically downward direction as follows:

Step 3

In this time interval (t = 0.05711 second) the distance travelled by ...
