Question: Two ice skaters, with masses of 30kg and 75kg , are at the center of a 50m -diameter circular rink. The skaters push off against each other and glide to opposite edges of the rink.
Part I: If the heavier skater reaches the edge in 30s, how long does the lighter skater take to reach the edge?
I want help to find how long the lighter skater takes to reach the edge.
