A truck of mass M is moved under a force F. The truck is then loaded with an object equal to the mass of the truck and the driving force is halved, then how does the acceleration change?

Case 1
F=Ma
=>a=F/M
Case 2
F/2=2M×a'
a'=F/4M
=a/4
Thus,acceleration becomes one-fourth.
Answer:
Force=mass x accelaration
Force/mass = accelaration
mass of truck before loading=M
and driving force=F
acceleration (before loading) =F/M
mass of the truck after loading=2M
and driving force after loading=1/2F
acceleration (after loading)=1/2F ÷ 2M
=F/4M
Thus, the accelaration reduced by a quarter(1/4)
