In a very busy off-campus eatery one chef sends a 249-g broccoli-tomato-pickle-onion-mushroom pizza sliding down the counter from left to right at 1.67 m/s. Almost simultaneously, the other chef launches a 341-g veggieburger-on-a-bun (with everything, but hold the horseradish) along the same counter from right to left at 2.31 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? At what speed does it move, in a positive number.
