Underneath the appropriate column of graphs from assignment 38.2, write an equation that solves for the variable in question (see below). write which model you used: newtonian force model, energy-interaction model, the momentum conservation model, if you introduce any new variables, clearly indicate what they mean.

Newton Equations are such as Force = Mass * Acceleration, Potential Energy= mass * acceleration of gravity* height, Force of gravity= universal gravitational constant(Mass of the earth* Mass of Object)/( Distance in between)^2, Kinetic Energy= 1/2Mass (velocity) ^2, Momentum = speed * Mass and Voltage= current * resistance, Energy= Mass * (speed of light)^2 and etc, yet all of these are models for solving physics and mathematics problems.

Basic math, of interest. He starts with 800 and gains 5% each year. 5% of 800 is 40.

800 + 40 = 840.
