Two forces, F, and F2, act at a point, as shown in the
picture. (Figure 1) Fı has a magnitude of 8.40 N and
is directed at an angle of a = 56.0° above the negative
x axis in the second quadrant. F2 has a magnitude
of 6.00 N and is directed at an angle of B = 54.1 °
below the negative x axis in the third quadrant
What is the force of Fx and Fy and F?

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.
