Expert Answer:

begin mathsize 12px style Given space that space
Mass space of space the space box space equals space straight m space equals space 50 space kg comma
Force space applied space equals space straight F space equals space 80 space straight N
We space know space that space
Force space equals space mass space cross times space acceleration
rightwards arrow space straight F space equals space ma
rightwards arrow space straight a space equals space straight F over straight m
space space space space space space space space equals space 80 over 50 space
therefore space straight a space equals space 1.6 space straight m divided by straight s squared
If space the space mass space is space halved comma space straight m space equals space fraction numerator 50 space kg over denominator 2 end fraction space equals space 25 space kg
therefore space straight a space equals space fraction numerator 80 space straight N over denominator 25 space kg end fraction space equals space 3.2 space straight m divided by straight s squared end style
