So if the velocity is -9m/s the absolute velocity is 9m/s?

would I use that to find the acceleration?

so the velocity after impact is -9m/s. would I use this to find the acceleration?

Homework Statement A ball moving westward at 36 m/s hits a wall and rebounds at 27 m/s, eastward. (a) What is the change Δv in the vector velocity? (This is effectively the velocity of the rebounding ball relative to an image of it passing through the wall unaffected. It’s not the same as the...
