Energy is required to accelerate a spaceship with rest mass

Reference no: EM13540231

a) How much energy is required to accelerate a spaceship with a rest mass of 112 metric tons to a speed of 0.445 c?

b) Every day our Earth receives 1.55×1022 J energy from the Sun. If we were able to use 1.05 percent of this energy to accelerate spaceships, then how many missions would be possible in one year?
