Question

A box rests on a frozen pond, which serves as a frictionless

horizontal surface. If a fisherman applies a horizontal force with magnitude 48.0 N to the box and produces an acceleration of magnitude 3.00 m/s², what is the mass of the box?

Answer 1

Solution.

$F=48.0 N;$

$a=3.00 m/s^2;$

$m-?;$

$a=\dfrac{F}{m}\implies m=\dfrac{F}{a};$

$m=\dfrac{48.0N}{3.00 m/s^2}=16.0 kg;$

Answer: $m=16.0 kg.$
