Calculating Velocity of a Hockey Puck

[nosh]

Homework Statement

A 0.160-kg hockey puck is moving on an icy, frictionless, horizontal surface. At t=0 the puck is moving to the right at 2.98m/s .

Homework Equations

Calculate the magnitude of the velocity of the puck after a force of 24.0N directed to the right has been applied for 5.5×10−2s .
If instead, a force of 12.5N directed to the left is applied from t=0 to t= 5.5×10−2s , what is the magnitude of the final velocity of the puck?
