A hockey puck with mass 0.160kg is at rest on the horizontal, frictionless surface of a rink. A player applies a force of 0.250N to the puck, parallel to the surface of the ice, and continues to apply this force for 2.0s.
1) What is the position of the puck at the end of that time?
2) What is the speed of the puck at the end of that time?
