In a very busy off-campus eatery one chef sends a 235-g broccoli-tomato-pickle-onion-mushro om pizza sliding down the counter from left to right at 1.65 m/s. almost simultaneously, the other chef launches a 351-g veggieburger-on-a-bun (with everything, but hold the horseradish) along the same counter from right to left at 2.47 m/s. the two delicacies collide head on at the given speeds–the counter is practically friction-free due to accumulated grease–and merge into a single, unbelievably savory serving. in what direction does the delectible dish move, if it moves at all?
