In all parts, consider the following situation. In a baseball game the batter swings and gets a good solid hit. His swing applies a force of 12,000N to the ball for a time of 0.70×10−3 seconds. A) Assuming that this force is a constant, what is the magnitude J of the impulse on the ball. B) What is the the shape of the net force vs. time graph? C) Why is the graph that shape?

F=12000N, t=0.7⋅10−3s  A) Impulse =F⋅t=12000⋅0.7⋅10−3  Impulse =8.4kg.ms  B) The net force versus time graph has a rectangular shape.  C) Area under grapgh give impulse  Area = lenght*breadth =0.7⋅10−3⋅12000=8.4kg.ms  ANs force is constant, so it is rectangular shape
