A Mountain bar has a mass of 6.7×10−2 kg and a calorie rating of 270 cal.

What speed would this candy bar have if its kinetic energy were equal to its metabolic energy? [Note: The nutritional calorie, 1 Cal , is equivalent to 1000 calories (1000 Cal ) as defined in physics. In addition, the conversion factor between calories and joules is as follows: 1 = 1000 Cal = 1KCal = 4186 J .]
