Constant of proportionality equation CCSS 2014 by Philip Palumbo - September 9, 2014 m d v d t = m g − k v 2 , where k> 0 is a constant of proportionality. The positive direction is downward. (a)Solve the equation subject to the initial condition v(0) = v0. (b)Use the solution in part (a) to determine the limiting, or terminal, velocity of the mass.
. Directly proportional variables are indicated graphically by a straight line passing through the origin of the coordinate plane. Once you understand these basic concepts, it is easy to identify directly proportional variables by using the equation of their line, or their values.
