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 5850 km
on a side and 35 km deep and that the rock
has an average mass density of 2750 kg/m3
.
the continent is moving at the rate of about
3.2 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 78 kg) has the same kinetic
energy as that of the continent.
what would his speed be?
answer in units of m/s.

At a certain instant after jumping from the airplane a, a skydiver b is in the position shown and has reached a terminal (constant) speed vb = 52 m/s. the airplane has the same constant speed va = 52 m/s, and after a period of level flight is just beginning to follow the circular path shown of radius ρa = 2330 m. (a) determine the velocity and acceleration of the airplane relative to the skydiver. (b) determine the time rate of change of the speed vr of the airplane and the radius of curvature ρr of its path, both as observed by the nonrotating skydiver.
