to solve this

Problem 2 (15 pts.): Friction force between an object and a surface is often described to be composed of three parts: static, Coulomb, and viscous friction, which are related to the velocity. Identify by looking at the plots with friction force as the output and velocity as the input, which of the friction force relationships shown in Figs. (a) and (b) are linear. Draw a third plot (c) that shows a combined curve of Coulomb + viscous friction versus velocity. Would this new plot be linear or nonlinear? Force Force Viscous friction Static Velocity Velocity 0) es Coulomb (a) (b)
