Question: 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 3.00 m/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 ofl2.0 N directed to the left is applied from t = 0 to t = 0.050 s, what is the final velocity of the puck?
