Two ice skaters stand facing each other at rest on a frozen pond. They push off against one another and the 47 kg skater acquires a speed of 1.92 m/s. If the other skater acquires a speed of 3.73 m/s, what is her mass in kilograms? Type your answer.. 5 1 point A car with a mass M is moving toward another car with a mass 2M on a frictionless surface. Both cars have a speed of 10 m/s. Subsequently, they collide and stick together. What is the final velocity of the two car system? V = ? 2M 2M M M BEFORE AFTER +X +3.3 m/s OO +5.0 m/s +10 m/s None of these O.O -3.3 m/s
