Question

In a very busy off-campus eatery one chef sends a 227-g broccoli-tomato-pickle-onion-mushroom pizza sliding down the counter from left to right at 1.55 m/s. Almost simultaneously, the other chef launches a 347-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?

Explanation / Answer

Assuming an ideal environment with zero friction and no air resistance.

Lets call force exerted for 1st pizza be F1

abd force exerted by pizza 2 be F2

both pizza will have twoi kinds of energy stored in them (in terms of physics) i.e. Potential and Kinetic energy

Both Potential and Kinetic energy are governed by Mass/ weight of Pizza and velocity.

Since Pizza 2 has higher mass and higher velocity it will have higher force, hence

F2>F1

given above, the Pizza will continue in the direction of Pizza 2 since its Force F2 is substantially higher than F1.
