The puck that required the greatest force to be stopped is puck C, followed by puck B and the least is puck A.

Applied force

The force needed to stop the pucks or applied to stop the pucks is determined by applying Newton's second law of motion as shown below;

F = ma

F = mv/t

where;

  • F is the applied force
  • m is the mass of the pucks
  • v is the speed of the pucks
  • t is the time

From the quation above, the applied force is directly proportional to the speed of the pucks. Thus, the greater the speed of the puck, the greater the required force to stop the puck.

Therefore, the puck that required the greatest force to be stopped is puck C, followed by puck B and the least is puck A.
