MULTISTEP A 3.0-kg block is traveling to the right (the direction) at and a second 3.0-kg block is traveling to the left at (a) Find the total kinetic energy of the two blocks. (b) Find the velocity of the center of mass of the twoblock system. (c) Find the velocity of each block relative to the center of mass. (d) Find the kinetic energy of the blocks relative to the center of mass. (e) Show that your answer for Part (a) is greater than your answer for Part (d) by an amount equal to the kinetic energy associated with the motion of the center of mass.

Chapter 4: Forces and Newton’s Laws of Motion 4.1 Motion and Forces Newton’s First Law of Motion: An object at rest will remain at rest, or moving in a straight line at constant speed will remain moving in a straight line at constant speed, unless acted upon by an external agent. A ‘force’ causes a CHANGE in motion (or attempts to cause a change!). A force is a push or...
