Question

You are part of a car accident investigative team, looking into a case where a car drove off a
bridge. You are using the lab projectile launcher to simulate the accident and to test your
mathematical model (an equation that applies to the situation) before you apply the model to the
accident data. We are assuming we can treat the car as a projectile.

Mock-up of accident:
T
h
L.
V
-R-
In the mock-up above, which variable is related to the horizontal displacement of the
car/projectile?
Does the car/projectile leave the bridge at an angle? (Yes/No) If yes, what is the
launch angle?
At the moment of launch -the instant when the car leaves the bridge: is the horizontal
component of the car's velocity (Vox) to the right, to the left or zero?
After launch while the projectile flies through the air, is the horizontal acceleration of
the projectile to the right, to the left or zero?
