I was asked this question by my daughter.
This takes place in space, with no other forces to slow it down. From a standing start, a rocket accelerates at 1 G for two hours before the engines shut down and coast. In feet per second, how fast is it going after one minute, one hour and when it shuts down its engines after two hours? I think the answers are: 1920 fps 115,200 fps 230,400 fps |
