Question

Prior to 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 several
rockets. Calculate the magnitude of force exerted by each rocket, called its thrust T , for the four-rocket propulsion system
. The sled’s initial acceleration is 49 m/s2
, the mass of the system is 2100 kg, and the force of friction
opposing the motion is known to be 650 N.
