If a stack of 1,008 alkali fuel cells in series generates 14,800 w of power, and each cell contributes equally to the power of the stack, how much power does each cell contribute? (write the answer to one decimal place.)

I got 14.7 W each

14,800 divided by 1,008 is 14.682539 which is 14.7 to 1dp. Sorry if this is wrong.

question: ray weighs 100 kilograms, his wrestling partner, bobby, weighs 50 kilograms. if ray moves at 4 m s , how fast will bobby have to run at him to apply an equal amount of kinetic energy?

answer: 8 m/s he needs to run twice as fast to keep up so he has some work to do

explanation:   if the mass has units of kilograms and the velocity of meters per second, the kinetic energy has units of kilograms-meters squared per second squared.
