Homework Statement



The force exerted on a 0.145 kg baseball by a bat changes from 0.0n to 1.0x10^4 N over 0.0010 s, then drops back to zero in the same amount of time. THe baseball was going toward the bat at 25 m/s.

a. Draw a graph of force versus time. What is the average force exerted on the ball by the bat?
b. what is the acceleration of the ball?
what is the final velocity of the ball, assuming that it reverses direction?

You need to make an attempt before we can help you. What have you tried thus far?
 
To solve this, I first used the units to work out that a= m* a/m, i.e. t=z/λ. This would allow you to determine the time duration within an interval section by section and then add this to the previous ones to obtain the age of the respective layer. However, this would require a constant thickness per year for each interval. However, since this is most likely not the case, my next consideration was that the age must be the integral of a 1/λ(z) function, which I cannot model.
