1. The problem statement, all variables and given/known data Anthony and Sissy are participating in the "Roll-a-Rama" roller-skating dance championship. While 75kg Anthony roller-skates backwards at 3m/s, 60kg Sissy jumps into his arms with a velocity of 5m/s in the same direction. m1= 75kg v1= 3m/s m2= 60kg v2= 5m/s v' = ? 2. Relevant equations The inelastic collision equation possibly? 3. The attempt at a solution (75kg)(3m/s) + (60kg)(5m/s)= (75kg+60kg)x 225kg*m/s + 300kg*m/s= 135kg(x) 525kg*m/s = 135kg(x) (525kg*m/s)/135kg = x 3.8m/s= x Is that correct?
