2. [10] A baseball, having a mass of 0.320 kg is struck by a baseball bat. Right before the ball collides with the bat, the ball has a velocity v1 of magnitude 14.0 m/s at an angle0 = 60° with respect to the y-axis as shown in the diagram. Right after being struck by the bat, the ball has a velocity v2 of magnitude 12.0 m/sin the direction of the positive y-axis. The ball is in contact with the bat for a time of1.90 ms. What is the magnitude of the average force that the bat exerts on the ball? (The influence of gravity should be ignored in this calculation.)
