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?

• Physics -

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

• Physics-shouldn't it be -20 instead of -22 -

Shouldn't it be -20,not -22

• Physics-could someone check -

Damon helped me to solve this problem but I think it adds up to -20 not -22, correct?

• Physics -

Change in velocity = Vf-Vi =6 - 14 = -8
m/s.
