The theory of special relativity explains the connection between space and time to objects that move in a straight line at a constant speed. The objects move at the speed of light. When an object approaches light speed, its mass is endless and cannot move faster than light. The most crucial postulate of Einstein's special relativity is that the laws of nature do not change in each frame of reference.

You are tasked with designing the propulsion system for Eagle Rocketry. You must first figure out how big the solid rocket propellent should be. You will use ammonium perchlorate propellent burning at 10 cm3 /sec to have an acceleration of 65 m/s2 vertically.a. If the competition requires your rocket to reach 30,000 ft, what is the minimum volume of propellent? Remember the rocket, for some time, travels up after the rocket engines turn off. If you know how long the rockets are on for you can multiply this by the volume burn rate. Graphing the velocity versus time and knowing what the area under that curve represents can save you a lot of time and algebra
