In this lab you measured the kinetic energy of a car (KE, in Joules) at several velocities (m/s). At the beginning of the lab the car was at rest (v = 0 m/s) and had no kinetic energy. At v = 1.0 m/s, the car had KE = 5.1 J. At v = 2.0 m/s, the car had KE = 19.6 J. At v = 3.0 m/s, the car had KE = 45.1 J. Finally, at v = 4.0 m/s,...

A mass (m) moves along the x-axis with velocity 2v. Another particle of mass (2m) moves with velocity v along the y-axis. 1) If the two objects collide inelastically and merge, how much kinetic energy is lost to heat? 2) If instead they collide elastically and it turns out that m still moves purely along the x-axis, what is it's velocity in the final state? It may help to find the velocities of these particles in the center of mass...
