15.28: On a frictionless horizontal surface, two bodies make ahead-
31q 2nb5mgdz pon collision and stick together. Body 1 has a mass of 3.5 kg and initially moves to the right with speed 7.0 m/s. Body 2 initially is at rest. A graph of the
zqm3db2ng 1 5pforce exerted onto Body 2 from Body 1 during the collision is shown.
How much kinetic energy was transformed to other kinds of energy from the collision?
