4B.3

Postby 905373636 » Sun Jan 26, 2020 11:49 am

This problem involves 982 J = 492 J + w so I calculated the answer to be 490J, but the back of the textbook says its 90 x 10^2 J. Could someone please explain if that's correct?

My textbook says the answer should be 4.90x102 which is the answer you have. I believe your answer is correct.
