Homework answers / question archive / In all parts, consider the following situation
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 12,000 N to the ball for a time of 0.70x10^-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 =12000 N , t =0.7*10^-3 s
A) Impulse = F*t = 12000*0.7*10^-3
Impulse = 8.4 kg.m/s
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 = 8.4 kg.m/s
ANs force is constant, so it is rectangular shape
