SUMMARY
The problem involves a 20 kg crate being lifted by an upward force of 200 N. To determine the crate's upward acceleration, the formula a = F ÷ m is applied. The correct calculation yields an acceleration of 0.2 m/s², confirming that the net force acting on the crate is indeed 200 N. The confusion arises from miscalculating the net force and not accounting for gravitational force acting on the crate.
