1 Newton = 1 kg * m/s^2
80kg (175 lbs)
80kg in earth's gravity (9.8m/s^2) creates 784 Newtons of downward force.
1,000 N engine (enough to overcome rocket weight)
The upward force is 216N.
The motor runs for 1 second.
What is the speed of the vehicle?
216N * 1s = 216 kg m/s (Unit of momentum)
216kg m/s / 80 kg = 2.7m/s
What is the altitude of the vehicle?
position = acceleration * time^2 / 2 (from two rounds of integration)
2.7 * 1^2 / 2 = 1.45m
