A hockey puck with mass 0.150 kg is at rest at the origin on a horizontal, frictionless surface of the rink. At t=0, a player applies a force of 0.250 N to the puck, parallel to the X-axis, and continues to apply the force until t = 2.00 s. What are the position of the puck at t=2.00s? ...

A hockey puck with mass 0.150 kg is at rest at the origin on a horizontal, frictionless surface of the rink. At t=0, a player applies a force of 0.250 N to the puck, parallel to the X-axis, and continues to apply the force until t = 2.00 s. What are the position of the puck at t=2.00s? If the same force is again applied at t=5.00s, what are the position and speed of the puck at t= 7.00s?
