# PHYSICSSSS

A train engine pulls out of a station along a straight horizontal track with five identical freight cars behind it, each of which weighs 88.0 kN. The train reaches a speed of 13.0 m/s within 6.50 min of starting out. Assuming the engine pulls with a constant force during this interval, and ignore air resistance and friction on the freight cars. Find the tension in the coupling between cars 2 and 3??? Answer in kN please
