Problem: the article describes the different between a crash with no helmet and a crash with a helmet. based on the article, 1) determine the impulse of a crash with a helmet (assume the force is 45 n) and 2) determine the impulse of a crash with no helmet (assume the time of impact is now 1.5 ms and the force is still 45 n). show your work with formula, substitution, and answer with units.

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.
