At the center of a 50-m-diameter circular ice rink, a 79 kg skater traveling north at 2.9 m/s collides with and holds onto a 65 kg skater who had been heading west at 3.3 m/s .
How long will it take them to glide to the edge of the rink?
Where will they reach it? Give your answer as an angle north of west.
Here ,
for the final speed
north is the positive y direction
west is the positive x direction
(79 + 65) * v = 79 * 2.9 j + 65 * 3.3 * i
solving for v
v = 1.59 j + 1.49 i
v = 2.18 m/s at 47 degree
for the time taken = 25/2.18 = 11.5 s
the time taken for them to reach the edge is 11.5 s
they will reach at 47 degree north of west

Two ice skaters, with masses of 50.0 kg and 85.0 kg, are at the center of a 30.0 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 10.0 s, how long does the lighter skater take to reach the edge?
Two ice skaters, with masses of 50.0 kg and 65.0 kg , are at the center of a 60.0 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 30.0 s , how long does the lighter skater take to reach the edge?
Two ice skaters, with masses of 30.0 kg and 65.0 kg , are at the center of a 30.0 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 20.0 s , how long does the lighter skater take to reach the edge?
Two ice skaters, with masses of 50.0kg and 65.0kg , are at the center of a 40.0m -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 30.0s , how long does the lighter skater take to reach the edge? Express your answer with the appropriate units.
Three ice skaters meet at the center of a rink and each stands at rest facing the center, within arm's reach of the other two. On a signal, each skater pushes himself away from the other two across the frictionless ice. After the push, skater A with mass mA = 75.0 kg moves in the negative y-direction at 4.00 m/s and skater B with mass mB = 80.0 kg moves in the negative x-direction at 3.50 m/s. Find the x-...
