Mоdel rоcket engines аre rаted by their thrust fоrce аnd by the impulse they provide. You can use this information to determine the time interval at which the engines fire. Two rocket engines provide the same impulse. The first engine provides 6 N of thrust for 4 s; the second provides 8 N of thrust. For how long does this second engine fire? It is NOT necessary to show work or reasoning for this problem.
