... Acceleration = a = 5 m/s/s [Forward] F= ma = (100 kg)(5 m/s/s) F= 500 kg m/s/s = 500 Newtons 2. If I push on a box with a force of 10 Newtons [East] and you push with 15Newtons due west, the box will have a net force of 5-Newtons to the west. This net force of 5-Newtons due west will cause the block ...
