We can calculate the kinetic energy of any moving object with a very simple formula: kinetic energy = 1/2 mv^2 ,where m is the object's mass and v is its velocity or speed. Table Energy Comparisons shows that metabolizing a candy bar releases about 10^6 joules.
A How fast must the candy bar travel to have the same 10^6 joules in the form of kinetic energy? (Assume the candy bar's mass is 0.2 kilogram.)
B Is your answer faster or slower than you expected?
