# 1) the current theory of the structure of the

earth, called plate tectonics, tells us that the

continents are in constant motion.

assume that the north american continent

can be represented by a slab of rock 4050 km

on a side and 29 km deep and that the rock

has an average mass density of 2750 kg/m3

.

the continent is moving at the rate of about

4.8 cm/year.

what is the mass of the continent?

answer in units of kg.

005 (part 2 of 3) 10.0 points

what is the kinetic energy of the continent?

answer in units of j.

006 (part 3 of 3) 10.0 points

a jogger (of mass 63 kg) has the same kinetic

energy as that of the continent.

what would his speed be?

answer in units of m/s.

Alarge reservoir supplies water for a community. a portion of the water supply system is shown. water is pumped from the reservoir to a large storage tank before being sent on to the water treatment facility. the system is designed to provide 1310 l/s of water at 20oc. from b to c the system consists of a square-edged entrance, 760 m of pipe, three gate valves, four 45o elbows, and two 90o elbows. gage pressure at c is 197 kpa. the system between f and g contains 776 m of pipe, two gate valves, and four 90o elbows. all pipe is 508 mm diameter, cast iron. calculate the average velocity of water in the pipe, the gage pressure at section f, the power input to the pump (its efficiency is 74 percent), and the wall shear stress in section fg.
