Arocket is launched at an angle of 39◦ above the horizontal with an initial speed of 90 m/s. it moves for 7 s along its initial line of motion with an acceleration of 19 m/s 2 . at this time its engines fail and the rocket proceeds to move as a projectile. the acceleration of gravity is 9.8 m/s 2 . find the maximum altitude reached by the rocket. answer in units of m.

Y=1370.23m

Explanation:

The motion have two moments the first one the time the initial velocity is accelerating then when the engines proceeds to move as a projectile

Now the motion the rocket moves as a projectile so:

Now the final velocity is the initial in the second one

The maximum altitude Vf=0

So total altitude is both altitude of the motion so:

force required to detach it is given by

charges are taken to be fundamental charge

now we have

so above is the minimum distance at which it will detach

c) power lifting, will be your answer.
