Ablock of mass m = 0.775 kg is fastened to an unstrained horizontal spring whose spring constant is k = 83.6 n/m. the block is given a displacement of +0.113 m, where the + sign indicates that the displacement is along the +x axis, and then released from rest. what is the force (magnitude) that the spring exerts on the block just before the block is released?

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.
