Answer:
1.8 N to the north
Explanation:
By the second Law of Newton, the net force is equal to
F = ma
Where m is the mass and a is the acceleration. Replacing m = 2000g = 2kg and a = 0.9 m/s², we get that the net force is
F = (2 kg)(0.9 m/s²)
F = 1.8 N
So, the net force acting on the puck is 1.8N to the north because the puck is decelerating.
