Question
A bullet is found embedded in the wall of a room 2.4 m above the floor. The bullet entered the wall going upward at an angle of 13°. How many meters from the wall was the bullet fired if the gun was held 1.3 m above the floor? (Round your answer to two significant digits.)

since the distances are so short, and the speed of the bullet is so great, we can treat the path of the bullet as a straight line. So,
(2.4-1.3)/x = sin13°
x = 1.1/sin13° = 4.8899
so, the gun was about 5 meters away.
(2.4-1.3)/x = sin13°
x = 1.1/sin13° = 4.8899
so, the gun was about 5 meters away.
