A 40kg skater moving at 4 m/s overtakes a 60kg skater moving at 2 m/s in the same direction and collides with her. The two skaters stick together. What is their final speed?

conservation of momentum
40*4+60*2= (100)V solve for V

Jason (please help)
So the answer is 100V

No. divide each side by 100
(160+120)/100 = V
You have to calculate that.
