On a moving cart, an object of mass m is connected to the cart with
spring and damper. The displacement of the cart and the object is
determined based on the fixed coordinate system of each ground, and
there is no friction between the object and the cart. Set up
equations of motion and guide them into differential equations m=1
[kg], k=2 [N/m], c= 3[N/m/sec]

A mass m = 5 kg is connected to an ideal massless spring of spring constant k = 100 N/m. At initial time t = 0 s, the mass passes the equilibrium position moving to the left (defined as the negative x direction) with a velocity vx0 = -5 m/s. Part (a): What is the first time after the initial time that the mass will be at the rightmost displacement? What is the quickest approach to this problem?
