# Problem: Consider two objects (Object 1 and Object 2) moving in the same direction on a frictionless surface. Object 1 moves with speed v1 = v and has inertia m1 = 2m. Object 2 moves with speed v2=2√v and has inertia m2=m. Which object has the larger kinetic energy? Which object has the larger kinetic energy? a. Object 1 has the greater kinetic energy. b. Object 2 has the greater kinetic energy. c. The objects have the same kinetic energy.

Kinetic energy:

$\overline{){\mathbf{K}}{\mathbf{E}}{\mathbf{=}}\frac{\mathbf{1}}{\mathbf{2}}{\mathbf{m}}{{\mathbf{v}}}^{{\mathbf{2}}}}$

KE1 = (1/2)(2m)(v2) = mv2
