Marble A of mass 3 . 00 k g moves exactly east at 9 . 00 m s and has a collision with marble B of mass 5 . 00 k g . If marble A moves to 60 . 0 ° north of east with a speed 8 . 00 m s and marble B moves to 15 . 0 ° north of east with a speed 5 . 00 m s after the collision, (a) what are the magnitude and direction of the velocity of marble B before the collision and (b) what are the magnitude and direction of the impulse from marble A to marble B? (c) Quantitatively determine whether the collision is elastic or in-elastic. (Ignore friction on the ground.) If marble A of mass 3 . 00 k g moves exactly east at 9 . 00 m s and marble B of mass 5 . 00 k g moves with a velocity determined in (a), (d) what are the magnitude and direction of the velocity of the marbles and (e) what is the change of kinetic energy in the system consisting of marbles A and B if both marble A and marble B stick together after the collision? fig2_q12_t3.jpg
