Kinetic Energy and Relative Motion
Two identical objects, A and B, each of mass m, move in opposite directions with speeds vA and vB relative to the ground. The total kinetic energy of the system, as measured by a ground-based observer, is 3mv². What is the kinetic energy of object B as measured from the reference frame of object A?
A
Cannot be determined from the given information
B
4mv²
C
2mv²
D
3mv²
