If a ball is thrown into the wall at 14 m/s and comes off at 6 m/s, what is change of velocity of the ball?

I think it would be 14-6 = (-8 m/s) Is that correct?

from +14 to -6 is -22

final = -6

original = 14

final - original = -6 -14 = -22

Physics-shouldn't it be -20 instead of -22 - Russ, Wednesday, January 5, 2011 at 4:58pm
