In a physics experiment, Stan has two lab carts. The blue lab cart has a mass of 0.5 kg and the red cart has a mass of 2.0 kg. In one experiment, Stan set the two carts at rest
on the track. He pushes in the plunger between them and releases it. He uses a
stopwatch to determine that after he releases the plunger, the red cart rolls to the right
at a velocity of 4 m/s.
Determine the velocity of the blue cart after the explosion.

Consider a one meter long horizontal pipe with a constant 100 cm^2 cross sectional area. water flows rightward into the pipe at x = 0 with flow velocity 02m/sec at every point within the pipe intake area. at x=1, the rightward flow rate is 0.192 m/sec. assume the water is a conserved quantity in the pipe, so there must be a leak (a sink) somewhere in the pipe. 1. compute net volumetric flow of the source if the system to be in equilibrium. 2. now assume the pipe in the problem has no leaks. compute the net volumetric rate of change for the system.
