Thus, if x = 4, assuming the MKS units system for physics, the displacement is 77 m, the velocity is 30 m/s, and the acceleration is 6 m/s<sup>2</sup>. | Thus, if x = 4, assuming the MKS units system for physics, the displacement is 77 m, the velocity is 30 m/s, and the acceleration is 6 m/s<sup>2</sup>. |
