20. PART-I: Two gliders with different masses move toward each other on a frictionless (shown Figure). After they collide glider B has a final velocity of +2.0 m/s. What is velocity of glider A? How do the changes in momentum, in velocity and in kinetic energy e VAL = 2.0 m/s vRx = -2.0 m/s (a) Before collision m, = 0.50 kg mp = 0.30 kg (b) Collision B Uaz = 2.0 m/s (c) After collision B PART-II: If the collision completely 'inelastic', what is the final velocity of glider A? Ho changes in momentum, in velocity and in kinetic energy compare? PART-III: If the collision completely 'elastic', what is the final velocity of glider A? Hov changes in momentum, in velocity and in kinetic energy compare?
