by conservation of momentum
mu = Mv
70x0.69 = 0.88xM
M = 48.3/0.88
M = 54.886 kg

Two ice skaters stand facing each other at rest on a frozen pond. They push off against one another and the 48-kg skater acquires a speed of 0.69 m/s. If the other skater acquires a speed of 0.87 m/s, what is her mass? ____kg
Three ice skaters meet at the center of a rink and each stand 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 = 80.0 kg moves in the negative y-direction at 3.50 m/s and skater B with mass mB = 75.0 kg moves in the negative x-direction at 4.00 m/s. Find the x-...
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.
Linear Momentum- Chapter 9 #6 ( 5 points) Two ice skaters moving together at a speed of negative 1.0 m/s push off against one another. The 45-kg skater acquires a speed of positive 0.375 m/s. What speed does the 60- kg skater acquire?
#4-7 Two ice skaters stand facing each other at rest on a frozen pond. They push off against one another and the 48 kg skater acquires a speed of 0.69 m/s If the other skater acquires a speed of 0.81 m/s, what is her mass in kilograms? kg My Notes Ask Your Teacher -/2 points HAFColPhys1 8.2WA019.
