two ice skaters are gliding together along the ice moving at a constant velocity

Question

two ice skaters are gliding together along the ice moving at a constant velocity (sliding without exerting a force). So they are initially moving at the same speed. skater 1 is 60kg and skater 2 is 85 kg. Skater 1 pushes skater 2 forward in the same direction they were initially moving. After the push skater 1 has velocity= 0. and skater two is moving at 1.8m/s after the push. Assume friction is neglected. What i the initial speed of both skaters?

a).75m/s
b) 3.07 m/s
c) 1.06 m/s
d) 2.55 m/s
e) 1.27 m/s
f) .744 m/s
g) .529 m/s

Explanation / Answer

60+85)V=85*1.8 v=1.06
