Two kids are roller skating. amy, with a mass of 55 kg, is traveling forward at 3 m/s. jenny, who has a mass of 40 kg, is traveling in the opposite direction at 5 m/s. they crash into each other and hold onto each other so that they move as one mass. how fast are they traveling? show your work.

Amy's weight = 55 kg also Amy's velocity = 3 m/sec. And Jenny's weight = 40 kg Jenny's velocity = -5 m/sec. their final mass = 55+40 = 95 kg is their final velocity that we want to find out.
Ect. but in conclusion the answer is 7/19 m/sec.

I hope this is correct >w< if it's not I am really sorry I mist up.

Cwill be your correct answer
