The equation K = mv2 represents the energy an object has based on its motion. The kinetic energy, K, is based on the mass of the

object, m, and the velocity of the object, v. Lashandra is given K and v for 10 different objects. In order to make solving more efficient, she solves the equation for m : m = . After attempting to determine the mass of a few objects, Lashandra realizes there must be something wrong with her formula. What is Lashandra’s error?

Kinetic energy<span> is the energy of motion. An object that has motion - whether it is vertical or horizontal motion - has </span>kinetic energy<span>. It is expressed as:

KE = mv^2 / 2

Therefore, her error would be that he lack the factor 1/2 in her formula. Hope this answers the question. Have a nice day.</span>
