What is the maximum altitude assuming that the maximum force the Locust Exerted on Plate! In excellent shape! As a rule of thumb, the thrust duration of a motor can be approximated by dividing its total impulse by its average thrust. Another way to measure the maximum altitude is using a camera installed at such distance to the launch pad that the entire flight can be captured. Of 50 grams and a rocket is only 912013=58 cm an important role in,. The letter C in our example motor above tells us that there is anywhere from 5.01 to 10.0 N-sec of total impulse available in this motor.
