Question

A man pushes a box of mass 50 kg with a force of 80 N. What will
be the acceleration of the box due to this force? What would be the
acceleration if the mass was doubled? ​

Answer 1

case1- F= MA
80N=50 X A
A=80/50=1.6
case2- F/m=a
so Acceleration is inversly propertional to Mass
So if wld double the mass then accln will be half means 0.8
