wording..."about 0.0050 seconds" What exactly does that mean? What does the 0 following the .005 mean? If you instructor actually said that, I am amazed at his/her lack of understanding precision and significant digits.
a) wouldn't the acceleration be negative?
b)magnitude of force= a/m and in the direction opposite to initial motion (the negative direction).
The force on the catcher is just opposite to b.
Okay the answer I am getting for this is 36666.67 but it said this was wrong?
Maybe I am doing it wrong though
I did 5500/.150
and it did say that the acceleration was right as a positive number
