Ahockey puck is given an initial speed of 35 m/s on a frozen pond. the puck remains on the ice and slides 132 m before coming to rest. the acceleration of gravity is 9.8 m/s 2 . what is the coefficient of friction between the puck and the ice?

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.
