1. The problem statement, all variables and given/known data
Find the work done by nonconservative forces in stopping the plane. A 18000 {\rm kg} airplane lands with a speed of 92 {\rm m/s} on a stationary aircraft carrier deck that is 115 {\rm m} long. 2. Relevant equations W = FD 3. The attempt at a solution 18000 * 92 * 115 = 190440000 J Unless it's wanting 1.9 * 10^8 = 190000000 J (which seems wrong since detail is lost) (I don't think that's 2 significant digits.)

it was 1/2(m)(v)^2 or something.
The answer was 7.6 x 10 ^7 Thanks!

Yes, the units of the correct answer was in joules.
