so I took the square root of the 2.44 x 10^-10 1/s^2 to get 1.56 x 10^-5 1/s and i flipped the sign by 1/1.56 x 10^-5 1/s to get 64018.4 but then when i convert it back to hours it's only 17.8 hours when it is supposed to be 25.1 hours. Where did i make the mistake? thanks for the help

well i first calculated p 220w/3x10^8 which was 7.33 x 10^-7 then i divided that answer by 150kg to get 4.89 x 10^-9 which I'm assuming is my velocity from there i divided the distance from the ship which was 20m to get 2.44 x 10^-10 and then i divided 1/2.44 x 10^-10 to get my answer in seconds

i know watt is joules per second. In the back of my book the answer is 25.1 hours. But i still can't seem to get anywhere close to that answer. I even tried E=c*p

the answer is supposed to be 25.1 hours. When i used E=c*p i ended up getting 1250000 hours. Am i doing a simple calculation wrong?
