On a Differential Equation with Caputo-Fabrizio Fractional Derivative of Order 1 <β ≤ 2 and Application to Mass-Spring-Damper System

In this work, we investigate a linear differential equation involving Caputo-Fabrizio fractional derivative of order 1<β≤ 2. Under some assumptions the considered equation is reduced to an integer order differential equation and solutions for different cases are obtained in explicit forms. We also prove a uniqueness of a solution of an initial value problem with a nonlinear differential equation containing the Caputo-Fabrizio derivative. Application of our result to the mass-spring-damper motion is also presented.
