1 Newton = 1 kg * m/s^2

== Vehicle

80kg (175 lbs)

80kg in earth's gravity (9.8m/s^2) creates 784 Newtons of downward force.

== Motor

http://en.wikipedia.org/wiki/Model_rocket_motor_classification

Size J - 1,000 N (enough to overcome gravity)

== Launch

The upward force is 216N.

The motor runs for 1 second.

== Questions

What is the speed of the vehicle?

216N * 1s = 216m/s

What is the altitude of the vehicle?
