Physics help please? puck question?

I believe it would be 1 m/s because of newtons balls. The energy from one ball is transferred to the next until it reaches the last ball in line. The 0.241 kg puck lost 1 m/s, which means it was transferred to the 0.275 puck. as for the velocity, v=s+d, meaning velocity equals speed plus direction. So the answer is (1m/s at 28 degrees on the positive x axis) Just so you know, That's a 9th grade home school education that just answered you question. ;)
