A girl who weighs 30 kilos in an inline skating at the speed of 5 miles what is her kinetic energy?

The kinetic energy of the girl can be calculated using the formula: KE = 0.5 * mass * velocity^2. Converting her weight from kilos to pounds (1 kilo ≈ 2.205 pounds), she weighs approximately 66.1 pounds. Plugging in the values (mass = 66.1 lbs and velocity = 5 miles per hour), the kinetic energy can be calculated in joules.
