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?

A) Impulse $=F\cdot t=12000\cdot 0.7\cdot {10}^{-3}$
Impulse $=8.4kg.\frac{m}{s}$
B) The net force versus time graph has a rectangular shape.
C) Area under grapgh give impulse
Area = lenght*breadth $=0.7\cdot {10}^{-3}\cdot 12000=8.4kg.\frac{m}{s}$
ANs force is constant, so it is rectangular shape
