Hi, I'm a forgetful fish, at least I think I am...

A few weeks ago, I came across this question during physics tuition that made me laugh so I thought I might share with my dear readers.



The question was: Diagram 19 shows a 4kg fish swimming 1m/s swallows an absent minded 0.5kg fish swimming toward it at a velocity that brings both fishes to a halt immediately after lunch. What is the velocity of the smaller fish before lunch?

LOLS...the smaller fish was so absent minded that it swam right into the big fish's mouth making itself lunch?XD



Here's something I drew to go with it (inspired by Rui Zhi, cause she said the big fish's mouth was too small to fit the whole of the small fish). Which, come to think of it kinda makes sense.XP

Cheers~
