Two hockey pucks slide on nearly frictionless ice and collide in 1D. Puck A has mass mA=0.20 kgm_A=0.20\ \text{kg} and initial velocity vAi=+10 m/sv_{A i}=+10\ \text{m/s} (right). Puck B has mass mB=0.10 kgm_B=0.10\ \text{kg} and is initially at rest (vBi=0v_{B i}=0). After an elastic collision, Puck A is observed to move at vAf=+3.3 m/sv_{A f}=+3.3\ \text{m/s} (right). Taking rightward as positive, what is Puck B's final velocity vBfv_{B f} (from momentum conservation)?
