A cargo plane is flying horizontally at an altitude of 10000m with a velocity of

Question

800km/h when a cargo pallet falls out the back ramp.
(i) How long does it take to fall to the ground?
(ii) How far horizontally is the pallet from where it fell off when it hits the
ground?
(iii) How far is the pallet from the aircraft when it hits the ground assuming the
plane continues to fly horizontally at the same constant speed?

Answer 1

(i) h=gt²/2
t=sqrt(2h/g)=sqrt(2•10000/9.8)=45.2 s.
(ii)
v=800000/3600 = 222.2 m/s
s=vt =222.2•45.2 =10044 m
(iii) x=0 (since the horizontal speed of the cargo is constant)

Answer 2

Thank you so much
