Problem

Two bicycles have the same mass. Bicycle B moves twice as fast as bicycle A. Which statement about their kinetic energies is correct? (a) Bicycle B has eight times the kinetic energy of bicycle A.\text{Bicycle B has eight times the kinetic energy of bicycle A.} (b) Bicycle B has the same kinetic energy as bicycle A.\text{Bicycle B has the same kinetic energy as bicycle A.} (c) Bicycle B has four times the kinetic energy of bicycle A.\text{Bicycle B has four times the kinetic energy of bicycle A.} (d) Bicycle B has twice the kinetic energy of bicycle A.\text{Bicycle B has twice the kinetic energy of bicycle A.}
