A mass of 7 kg rests on a floor with friction. One force is applied vertically downward of 23 Newtons and another force is applied in the +x direction such that it just begins to move the mass. The force of 23 Newtons is then applied vertically upwards instead of downwards and another force is applied in the +x direction which just begins to move the mass that force is 141 Newtons less than the first case. What is the...

1) A mass of 8 kg rests on a floor with friction. One force is applied vertically downward of 21 Newtons and another force is applied in the +x direction such that it just begins to move the mass. The force of 21 Newtons is then applied vertically upwards instead of downwards and another force is applied in the +x direction which just begins to move the mass that force is 137 Newtons less than the first case. What is...
