Two gliders are moving on a horizontal frictionless air track. Glider 1 has mass m1 = 194.3 g and is moving to the right (positive x-direction) with speed 2.277 m/s. Glider 2 is moving to the left (negative x-direction) with a speed of 3.623 m/s. The gliders undergo a totally elastic collision. The velocity of glider 1 after the collision is -4.750 m/s.
What is the mass of glider 2?
