Go to http://www.archive.org/details/ThrillDriversChoiceProjectile and view the video.

This 1956 commercial for Chevrolet shows a troupe of men driving regular Chevrolet cars, not the

“souped-up models.” They perform a variety of tricks including, at about 0:34, a jump from one ramp to

another. This is a simple projectile motion problem.  Using the video of the jump:

1)      Estimate the time of flight:

2)      Estimate the launch angle:

3)      Estimate the car’s speed:

4)      Calculate the range:

5)      Calculate y_max:
