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 146 = (8 m/s) Is that correct?

from +14 to 6 is 22
final = 6
original = 14
final  original = 6 14 = 22

Physicsshouldn't it be 20 instead of 22  Russ, Wednesday, January 5, 2011 at 4:58pm
Shouldn't it be 20,not 22

Physicscould someone check  Russ, Wednesday, January 5, 2011 at 5:37pm
Damon helped me to solve this problem but I think it adds up to 20 not 22, correct?

Change in velocity = VfVi =6  14 = 8
m/s.
