Concept

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 magnitude of its momentum? a. Object 1 has the greater magnitude of its momentum. b. Object 2 has the greater magnitude of its momentum. c. Both objects have the same magnitude of their momenta.
