Two cars are traveling eastward on a highway, as shown in the left figure below. After 5.0 sec, the cars are side by side at the next telephone pole, as shown on the right. The distance between each of the poles is 70.0 m. Determine the following quantities: a) The distance the van has traveled during 5.0s interval
b) the distance limousine has traveled during the 5.0s interval.
c)The average velocity of the van during this 5.0s interval
d)the average velocity of the limousine during this 5.0s interval.

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.
