Question

1. A rocket is fired vertically from the launch pad with a
net accelevation of 20m/s². If the atmosphere is
approximately 100km thick and considering that the
acceleration is constant….

    Answer:

    Max height= 36000 meters

    Total Time = 120 seconds

    Explanation:

    0 = U – at

    U = at

    U= 20*60

    U= 1200 m/s

    MAX altitude would be

    (U²Sin²tita)/2g

    Max height= 1200² *( SIN90)²/(2*20)

    Time of FLIGHT

    2 * 1200/20

    2400/20

    120 sec
