6. 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?

on my assignment the answer was 8 m/s

hope this helps and thank you for the points :)

the average speed is 24.57 km/hr

i dont think you are wrong for wanting to get even with someone who did you wrong.

(i'm an eye for an eye kind of person) but if this person hurt you in a sexual way, i dont suggest doing anything to him. he should be taken to the proper authorities, you could go to jail depending on what you do. if it was something small like your sibling took your spot on the couch, than yea, i would get even with him by taking one of his favorite snacks lol. but i dont suggest you doing anything illegal.
