To evaluate collision safety in a modern transit system, engineers analyze the kinetic energy of two rapid-transit electric shuttle pods, Pod A and Pod B.
Pod A has a mass of mmm, travels at a speed of vvv, and has a kinetic energy of 120 kJ.
Pod B has a mass of 1.5m and travels at a speed of 0.8v0.8v0.8v.
What is the kinetic energy of Pod B?
