Answer:
6400 kg
Explanation:
An aeroplane, which together with its load has a
mass M=9600kg, is falling with an acceleration of
a = 5 m/s?. If a part of the load equal to m kg be
thrown out, the aeroplane will begin to rise with an
acceleration of a = 5 m/s². Find the value of m?
Force by Engine on Aeroplane = F
Force due to Gravity = Mg
Mg - F = Ma
=> F = M(g - a)
=> F = M(10 - 5)
=> F = 5M
Let say m kg weight is thrown
F - (M -m)g = (M-m)a
=> F = (M-m)(g + a)
=> F = (M -m)(10 + 5)
=> F = (M-m)15
5M = (M-m)15
=> M = 3M - 3m
=> 2M = 3m
=> m = 2M/3
=> m = 2 *9600/3
=> m = 6400
