Answer:
'acceleration will increase.'
Explanation:
We know that force on the rocket is given as follows
[tex]F=m\dfrac{dv}{dt}[/tex]
m=mass
v=velocity
t=time
F=force
[tex]F=m\dfrac{dv}{dt}[/tex]
F= m a
a=acceleration
[tex]a=\dfrac{F}{m}[/tex]
If the mass m decreases then the acceleration of the rocket will increase.
Therefore we can say that if the mass m decreases then the acceleration a will increases to maintain the constant force F.
The answer will be 'acceleration will increase.'
