If aerodynamic drag and transient changes in pressure are neglected, a closed-form approximation for the peak height of a rocket fired vertically can be expressed as shown here. It can be calculated using the equationacceleration = resultant force (newtons, N) divided by mass (kilograms, kg). )d25=4'L%';XHzR dB[RU""c. A short video of this failed launch with the flight timeline. These forces decelerate the rocket. Newtons first law states that a body at rest will stay at rest and a body in motion will stay in motion if a net external force acting on them is zero. This model rocket altitude calculator determines the estimated maximum flight altitude of a model rocket based on the distance between the spotter and the launch pad and the angle between the horizontal and the rocket at the top of its flight path (the apogee) assuming that the rocket is flying perfectly vertically. The thrust of each of the big white solid rocket boosters on the side was 12.5 million newtons, and the three main engines at the tail end of the bit that looks like a plane (the Space Shuttle orbiter) had a combined thrust of 5.5 million newtons. You are using an out of date browser. If we fly a rocket made from a kit, we can find it in the kit specifications. We now have a root. %PDF-1.4 % This means the total weight at lift-off is 2 million x 9.8, which is approximately 20 million newtons (20 mega newtons). Various devices can be used to measure the angle between the rocket (or any other high object) and the ground. There's probably no way you are going to be able to come up with a general equation that takes in all the different parameters this situation could have, but you can probably come up with something for a very specific case.
