Calculate the net acceleration acting on a 50 kg box being pushed across a horizontal floor. There is a 500 N normal force, a 200 N applied force, and a 60 N force of friction resisting any sliding motion. Assume g = 10 m/s2

In order for the bug to fly through the air a force has to push the bug forward. identify this force. how does the bug produce
