a 2000kg ship initially at rest in an inertial system is accelerated along a straight line for (3.16E7 seconds) by means of a photon rocket of 300MW power. If this is accomplised using a series of He-Ne lasers with wavelength=633 nm,
b) what is the speed of the spaceship after one year?
c)what distance does it travel
d) what fraction of energy released is in the kinetic energy of the spaceship
e) what is the wavelength of light observed in the initial inertial reference frame after 1 year?
