find the kinetic energy of an airplane traveling at a speed of 648 km/h if the mass of the airplane is 5,000 kg.

Answer 1

Convert the speed from km/h to m/s. A;lso convert the mass to kg. Then use the standard formula for kinetic energy, which you should know by now.

You are not going to learn physics by passing off easy questions like this for others to do. If you aren't willing to make an effort, seek help elsewhere.

Answer 2

holy crap that's savage
