An ideal spring hangs from the ceiling. a 2.15 kg mass is hung from the spring, stretching the spring a distance d = 0.0895 m from its original length when it reaches equilibrium. the mass is then lifted up a distance l = 0.0235 m from the equilibrium position and released. what is the kinetic energy of the mass at the instant it passes back through the equilibrium position?

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.

Two trains leave a station at the same time, train a travels at a constant speed of 16 m/s. train b starts at 8.0 m/s but accelerates constantly at 1.0 m/s squared. after 10.0 seconds, which train has the greater speed?
