Q. A flea pulls on a puck with force 7 microN at an angle of 30?. Another flea pulls on the puck with force 2 microN at an angle of -60?.

1) What is the magnitude of the net force on the puck? (I got 7.28 uN)

2) At what angle is the net force? (I got about 14.07 deg)

3) A third flea decides to pull the puck so that it will stop accelerating. What is the magnitude of the force with which it should pull and in what direction should the flea pull so that the puck stops accelerating?
