Homework Statement
This is extra credit, and the test has passed (no one got it), the prof said he'll still take efforts on it so here is my attempt.
A rocket sled is going down a test track at 180 km/hr (calculated to 50 m/s). It drops a snorkel into a trough of water. This diverts 30 kg/s of water vertically. The sled has mass of 500kg (including the snorkel and water in it).
The question is how far will the sled travel once it drops the snorkel.
I know I need to integrate from 50 to 0... but beyond that I don't know what vars to integrate in order to get something to plug into kinematic equations...
negate fluid+track+air friction.
