An autonomous freight pod is undergoing testing on a horizontal, frictionless vacuum track. The pod is propelled by an electromagnetic drive that exerts a constant forward thrust force of 4.850 kN4.850 \text{ kN}4.850 kN.
During a test run, the pod accelerates at a constant rate of 2.65 m/s2.
Calculate the mass of the freight pod.
