Trajectory Scenario

1. A bullet from a sniper struck and

killed a controversial political figure

who was waiting in a nearby car as a

passenger. Crime scene investigators

are unsure what floor of the building

the shot came from. The first floor of

the hotel is 25 ft. high. Each

subsequent floor is 15 ft. tall. Using

the measurements from the scene,

determine what floor of the building

the shooter came from.

Trajectory Scenario

2. There was an unusual stabbing at a local restaurant after two patrons got into a

disagreement. One patron shot an unknown gun twice, one bullet struck the victim

and the other bullet struck the sale sign of a nearby retail store. Using the security

cameras from across the street, forensic analysts determined the gun was shot

and half a second later it struck the sign. Forensic analysts want to determine the

velocity of the bullet using the measurements on the scene from the stray bullet to

help determine the type of gun used to convict the shooter. Velocity is calculated

as distance over time, and should be in meters per second. Round to the nearest

hundredth when necessary.

Trajectory Scenario

4. A reporter was shot while

driving a moving car.

Investigators are unsure if the

shooting was random or if it was

a targeted attack. A tree blocks

the visibility of the street after

65 feet, and would likely have been a random attack if the car was farther away

when hit. Because the car continued to move after the driver was struck,

investigators need to determine the distance the car was away from the building

when the shot occurred. Use the information provided to determine the distance of

the car.
