For positive constants a and b, the force between two atoms in a molecule is given f(r) = −a r2 + b r3 , where r > 0 is the distance between the atoms. note: a and b are upper case letters. (a) find f '(r) = (b) find the critical point for f(r). r = (c) find f ''(r) = (d) find the value of r so that f ''(r) = 0.

The guy wire bd exerts on the telephone pole ac a force p directed along bd. knowing the p must have a 720-n component perpendicular to the pole ac, determine the magnitude of force p and its component along line ac.
