Try this out. Use a calculator!

We can use the formula KE=0.5m*V^2. To find the kinetic energy (KE) of a payload of mass (m) 100 kg as it flies through the air at the velocity (v) of 55 m/s.

(Multiply 0.5 x the mass x velocity squared.)

Your answer will be in Joules (a measure of energy).

    Just subsitute and easy

    v=55m/s

    m=100kg

    KE = (0.5) (100kg) (55m/s) ^2

    KE = (50kg) (3025 m^2/s^2)

    KE=151250 J
