Nasa launches rockets eastward from cape canaveral to get a free velocity boost from the earth's rotation. if the earth's radius is 6371.0 km, the earth's mass is 5.97237x104 kg, the international space station is 400 km above the ground, and cape canaveral is 28 n of the equator, a) what is the earth's rotational speed at the equator (in km/h)? b) what is the orbital speed of the iss (in km/h)? what percent of their needed velocity do rockets get from being launched east at cape canaveral?

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.
