There is no force resisting motion.
However, we only need the puck to move at a constant velocity, that's, with zero acceleration.
From Newton's first law of motion, this scenario can be achieved without applying any external force.
A hockey pock is set in motion across a frozen pond. If ice friction and air resistance are neglected, the force required to keep the puck sliding at constant velocity is
A) equal to its mass times its weight
B) equal to its weight.
C) equal to its weight divided by its mass.
D) none of the above Nellie tosses a bail upward at an angle.
