15.28: On a frictionless horizontal surf
e,dc n 0c6dd7f1v 5eveace, two bodies make ahead-on collision and stick together. Body 1 has a mass of 3.5 kg and initially moves to the right with speed
cddde7e1n5, f60 vecv 7.0 m/s. Body 2 initially is at rest. A graph of the force 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?
