Question

Two cardboard boxes full of books are in contact with each other on a friction less table. Box H has twice the mass of box G. If you push on a box G with a horizontal force F, then box H will experience a net force of what?

Answer 1

i think the box h will experience a force equal to f

Answer 2

if u need explanation then i wanna tell the whole story

Answer 3

Answer 4

For these type of questions, you'll need Newton's second and third law.

as they are connected, the acceleration they experience is the same. Let mass of G be m and that of H be 2m.

total acceleration:
\(F=3ma\)
\(a=\frac{F}{3m}\)


For H, [f is the net force]
\(f=2ma\)
\(f=2m(\frac{F}{3m})\)
\(f=\frac{2F}{3}\)

As such the net force on H is two-thirds of F.
