A small spaceship, with a mass of 1500 kg (including occupants), is at rest in outer space with negligible gravitational forces acting on it. If the astronaut turns on a 10kW laser beam that points out of the ship into the deep of space, what speed will the ship attain in 1 day because of the momentum carried away by the beam?
W=J/s
10000W=10000J/s
10000*60*60*24= 864000000J
864000000=.5*1500v^2
v= 1073.31
where do i go from here?
