D1-18 Dievskiy

A body of mass m = 3 kg moves along a horizontal smooth surface along the x axis under the action of a force whose projection depends on time and is Fx = 6π cos 2t. At the initial time, x0 = 0 and the velocity projection vx0 = 2 m / s. Determine the value of the coordinate x of the body at time t = 0.5π s.
