8.9 . A 0.160-kg hockey puck is moving on an icy, frictionless, horizontal surface. At t=0, puck is moving to the right at 3.00m/s. (a) Calculate the velocity of the puck (magnitude and direction) after a force of 25.0 N directed to the right has been applied for 0.050 s. (b) If, instead, a force of 12.0 N directed to the left is applied from t=0,to t=0.050 s, what is the final velocity of the puck?
