Rocket Index \begin{align} If you measure the angle of inclination to the top of the rocket at its height point and find it to be 47 degrees, then the maximum height your rocket reached can be computed as follows: Height of rocket = 5 + 30 (tan 47) 37 feet. Answer: 0 m/s. In rocketry, the apogee is defined as the highest point of the rockets flight. Projectile, the focus of its parabolic path, and the circle drawn through the focus, Angle for max range from general range equation, Horizontal acceleration of an object moving down a parabolic track. It depends on the aspect. A test rocket starting from rest at point A is launched by accelerating it along a 200.0-m incline at 1.80 . Well, maybe thats a little melodramatic, but you want your rocket to perform just as well as it looks. v=uln(mim). A link to the app was sent to your phone.
