\fQuestion 17 (1 points) (515108) {Elastic Collisions) On a frictionless surface, a block of mass m1 : 2 kg moves at a velocity of vh- : +6 111/5 (towards the right) headed towards another block of mg : 1 kg moving at a velocity of U2?- : 3 m/s (towards the left). The rst block has an ideal massless spring mounted to its front side and so the collision between the blocks is perfectly elastic Which set ofnal velocities is consistent with this collision? l vlf=+3m/s ;v2f:+1m/s | olf:79m/s ;v2f:Om/s 88'6' 01f : Om/s 7112, = +9 m/s 0 l v1f=+3m/S :v2f=+3m/s I UleOm/S ;v2f:+6m/s
