At the end of this thrusting portion of the flight (1.7 seconds into flight time from liftoff), the model rocket is traveling at its maximum speed. The initial height from which we're launching the object is the maximum height in projectile motion. For example, in order for a rocket to be sent into space or a satellite into orbit, astronomers must use calculus to figure out how much fuel the rocket or satellite needs to accelerate to the correct velocity to break through the atmosphere. How to find the maximum height of a projectile? When the second observer hears the call, "Take Data", the Using these values: 0 = u 2 -2gs The net force upwards is 5000N, Also found my bitwise function that describes the position too: $$s(t)=2.5t^2, t<=5$$ $$s(t)=-5t(t-5)^2+25(t-5)+62.5, t > 5$$, Calculus - Equation for rocket max height.

Where U is potential energy, m is mass in kilograms, g is the acceleration due to gravity g=(9.81m/s2), and h is height is meters. It only takes a minute to sign up. Solve this equation assuming that the initial velocity, or v 0, is 10 feet per second as shown below: t=\frac {10} {a} t = a10 Since a = 32 feet per second squared, the equation becomes t = 10/32. What is the ideal rocket equation used for? The initial velocity, v0 = 200 ft/sec and the initial height is h0 = 0 (since it is launched from the ground). t = 1.5. f''(t) = -32, This means t=1.5 will be the time when the rocket will be . At the end of the two minutes the engines reduce the thrust they produce to a level just sufficient to maintain the vertical velocity achieved at that time.
