Question
If the force on a rocket, moving with a velocity 500m/s is 400N, then the rate of combustion of the fuel will be :
Options
A.0.8kg/sec
B.10.8kg/sec
C.8kg/sec
D.1.6kg/sec
Solution
We know that
Force =
[when v is conctant]
In the given case force = 400N;
v = 500 m/sec.
Force =
[when v is conctant]
In the given case force = 400N;
v = 500 m/sec.
