1.What is the net force accelerating a 5.0 kg cannonball from rest to 150 m/s [W], if the applied force acts for 0.05s?
2. A 500 g hockey puck experiences an applied horizontal force of 50 N [W] as it slides across the ice with an acceleration of 2.3 m/s2 [W] against the force of friction. Determine the magnitude and direction of the frictional force acting on the hockey puck.
