Thanks! This is what happens when I don't get enough sleep, I leave out a factor of 1/2! The box takes sqrt(2) seconds to reach 10 meters, which gives a final velocity of 14.14 m/s. The kinetic energy is indeed 1000 Joules. Sorry and thank you!

I have the following problem: "A box with a mass of 10 kg is accelerated by 10 m/s/s over a distance of 10 meters. What is the kinetic energy of the box (assuming no friction)" Using work... Work = K.E. F * D = K.E. m*a*D = K.E. = 10 kg * 10 m/s/s * 10 m = 1000 Joules However, using...
