An astronaut is preparing calculations for a flight to the Moon. The combined mass of the crew, all equipment, fuel, and the rocket is 1.15x105 kg on the launch pad. a. The rocket's engines produce a combined 1.25×10° N of thrust. Is this enough to lift the rocket and its payload? What if the engines produced 1.10×10° N of thrust? b. What is the minimum force the rocket needs to exert in order to lift off the ground and accelerate upward? (use three significant figures, in scientific notation) c. To return to Earth, the crew must take off from the Moon, where gravity is one-sixth that of Earth. Since most of the mass of the rocket is fuel, assume that three-fourths of the mass was lost in the journey to the Moon. How much force does the rocket need to exert in order to lift off the surface of the Moon?
