What is the change in the gravitational potential energy of a Boeing 767 jet as it soars from the runway up to a cruising altitude of 10.2 km? Assume its mass is a constant 2.04×105 kg.
answer please in joules. thanks

  • physics -

    m g h = 2.04*10^5 * 9.81 * 10.2*10^3

  • physics -

    Potential Energy = mgh
    where m is mass
    g is gravity
    h is height (should be in meters)

    PE = mgh
    PE = (2.04 x 10^5 kg)(9.8m/s^2)(10200m)
    PE = 2.04 x 10^10 J
