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
Homework Answers
here linear momentum remain conserve
initiaaly they are at rest
after they push against each other
0 = m1v1 - m2v2
m1v1 = m2v2
m2 = m1v1/v2
m2 = 48 * 0.69/0.87
m2 = 38.07 kg

Two ice skaters, with masses of 73kg and 55kg , stand facing each other on a 18-m-wide frozen river. The skaters push off against each other, glide backward straight toward the river's edges, and reach the edges at exactly the same time. how far did the 73kg skater glide?

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-...
