A 15.0 kg object moving in the +x direction at 5.5 m/s collideshead-on with a 11.5 kg object moving in the −x direction at 4.0 m/s.

Part A-

Find the final velocity of each mass if the objects sticktogether.

Express your answers using two significant figures. Enter youranswers numerically separated by a comma.

Part B-

Find the final velocity of each mass if the collision iselastic.

Express your answers using two significant figures. Enter youranswers numerically separated by a comma.
