a model rocket is launched straight upward with an initial speed of 50.0 m/s
Ques: A model rocket is launched straight upward with an initial speed of 50.0 m/s. It accelerates with a constant upward acceleration of 2.00 m/s^2 until its engines stop at an altitude of 150 m.
a) What can you say about the motion of the rocket after its engines stop?
b) What is the maximum height reached by rocket?
c) How long after liftoff does the rocket reach its maximum height?
d) How long is the rocket in the air?
2.77 โข During your summer internship for an aerospace com- pany, you are asked to design a small research rocket. The rocket is to be launched from rest from the earth's surface and is to reach a maximum height of 960 m above the earth's surface. The rock- et's engines give the rocket an upward acceleration of 16.0 m/s during the time T that they fire. After the engines shut off, the rocket is in free fall. Ignore air resistance. What must be the value of T in order for the rocket to reach the required altitude?
A model rocket is launched straight upward with an initial speed of 70.0 m/s. It accelerates with a constant upward acceleration of 2.50 m/s2 until its engines stop at an altitude of 200 m.(a) What is the maximum height reached by the rocket?(b) How long after lift-off does the rocket reach its maximum height?
