Problem 40P
Two ice skaters, with masses of 50 kg and 75 kg, are at the center of a 60-m-diameter circular rink. The skaters push off against each other and glide to opposite edges of the rink. If the heavier skater reaches the edge in 20 s, how long does the lighter skater take to reach the edge?
ANSWER:
Step 1 of 2
The masses of two ice skaters are,
.
The diameter of the disk is,
So, the radius will be,
.
Both gliding to the opposite sides of the disk.
So, each of the person has to travel the distance of 30 m.
The heavier person of mass 75 kg, reached at the edge in 20 s.
So, his velocity is,
.
