Could you help me figure out this problem. I am a Middle School Teacher
and one of my students gave it to me, and before I give them my answer,
I'd like some outside input.
Thanks,
Ryan
Imagine a train truck (just a single carriage freewheeling without a
motor) full of water travelling horizontal, smooth (frictionless) track,
at constant velocity. There is a leak in the truck and water is pouring
slowly (at a constant rate) through the hole. What will happen to the
velocity of the truck? Your answer should refer to the principles of
conservation of momentum and energy. Please imagine you are writing this
answer for a highly able grade 9 student.
