Question

Before manned space flights, rocket sleds were used to test aircraft, missile equipment, and physiological effects on human subjects at high speeds. They consisted of a platform that was mounted on one or two rails and propelled by multiple rockets.

There is a new rocket sled with two rockets being tested. The sled weighs 1780 kg, and accelerates at 55 m/s². With the new design you can ignore wind resistance, but there is a kinetic coefficient of friction between the rocket sled and track that is measured to be 0.06. What is the thrust of each engine of the rocket sled?

Draw a FBD.
