Astudent attaches a rope to a 20.0 kg box of books. he pulls with a force of 90.0 n at an angle of 30 degrees with the horizontal. to make his job easier, he oiled the bottom of the box, reducing the coefficient of friction to 0.250. what is the magnitude of the acceleration of the box?

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.
