A 160 kg hockey puck is moving on a icy, frictionless, horizontal surface.
at t=0 the puck is moving to the right at 3m/s
1) Calculate the velocity of the puck(magnitude and direction) after a force of 25N directed to the right has been applied for 0.050s
2)If instead, a force of 12N directed to the left is applied from t=0 to t=0.050s, wht is the final velocity of the puck?
The momentum on a frictionless surface is determined. The expert calculates the velocity of the puck after a force is directed on it.
