Question

2.77During your summer internship for an aerospace com F pany, you are asked to design a small research rocket. The rocket is to be launched from rest from the earths surface and is to reach a maximum height of 960 m above the earths surface. The rock- ets 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?

Section 2.6 Velocity and Position by Integration 2 51 CALC A rocket starts from rest and moves upward from the surface of the earth. For the first 10.0 s of its motion, the verti- cal acceleration of the rocket is given by ay-(2.80 m/s), W the +y-direction is upward. (a) What is the height of the rocket above the surface of the earth at t = 10.0 s? (b) What is the speed of the rocket when it is 325 m above the surface of the earth? here
