The kinetic energy, KE, of an object travelling at v velocity can be modeled by the equation KE = mv2, where m is the mass of the object. If an object is moving at a velocity of 9, and it has a kinetic energy of 120, about how great is the object's mass?
(A) Between 0 and 1
(B) Between 1 and 2
(C) Between 2 and 3
(D) 6
(E) 13
