Given:

mass = 6 kg

v = 20 m/s

Determine the kinetic energy.

Formula for kinetic energy:

Ke = ½ mv^2

Solution:

Substitute the given values of m and v to the formula for the kinetic energy.

Ke = ½ m/v^2

Ke = ½ (6 kg)(20 m/s)^2

Ke = (3kg)(200 m^2/s^2)

Ke = 600 Joules

Final answer:

Ke = 600 Joules
