A supertanker of mass 1.7 x 10⁷ kgis being towed by two tugboats which apply forces at equal angles of 35^owith respect to the tanker's axis. The tensions in the towing cables is 1.35 x 10⁴ N. In addition, the tanker's engines provide a forward drive force of 5.7 x 10⁴ Nand the water applies an opposing force of 4 x 10⁴ N. Find the resulting acceleration of the tanker.
