Two sleds tied together are pulled across an icy surface with an applied force of 150 N [E]. The mass of the first sled is 18.0 kg and the mass of the last sled is 12.0 kg. The coefficient of kinetic friction for each sled is 0.20. Find the magnitude of the tension in the rope connecting the two sleds.
