to find velocity of spacecraft and acceleration, Physics

Assignment Help:
find acceleration of spacecraft will changed during journey and velocity and displacement if formula for displacement " s " and velocity V
S=ut +1/2 at.... (t to power 2)
V= u+at , u is initial velocit, t is time , a is acce.
F= ma , w-FD =ma ...1
W=mg ....2
m is mass of spacecraft in kg
g= (40x10power 7)/(6371+H)power 2 in M/S power 2 ..
FD is drag force in newton , h is high of spacecraft above the earth in km,
drag force is proportional to velocity and is giving ;
FD=1/2 C P A V (power to 2 for V)
C is drag coefficient= 0.7,
P= air density = - H/71+1.4 in kg/m(power to 3 for m),
A= effective cross sectional area =5m(power to3 for m)....
For H>100 km
for 0can you please solve this question
,thanks
