A particle of mass 2.0 kg moves under the influence of the force F(x) = (3/√x) N. If its speed at x = 2.0 m is v = 6.0 m/s, what is its speed at x = 7.0 m?

rises to a height of 3m above the upper reservoir at a distance of 240m from the entrance before falling to the lower reservoir. If the pipe is 1.2m in diameter, what will be the discharge and the pressure at the highest point of the pipeline? Note that the entry to both reservoirs is sharp (k 0.5) and the frictional coefficient f= 0.01 h%=D3m AC = L, = 240m CB = L2 =480 m AB = L = 720 m Diam = d =1-2 m V = Pipe velocity f =0-01
