3} Two particles of equal mass or have the following position and velocity vectors: T| = i + j 1"1 = 21 r1=j+k '91 =j+k a] Calculate the kinetic energy by adding the energy of each particle [1 point] hi Calculate the reduced mass it of the system [1 point} c] Calculate kinetic energy using: 1 1 T=M3m v2 2 1.! +2.14! where M is the total mass of the system. vm is the center of mass velocity. and v is the relative velocity between the particles {1 point}
