In an experiment mary compares a collision of two kilogram steel balls with a collision of the 1-kilogram foam rubber balls. she makes sure
that except for the material, the two collisions are the same. mary finds that the force of impact of the steel ball collision is greater than the
force of impact of the foam rubber ball collision
rom her force measurements, mary concludes that the foam rubber balls acceleration during the collision was
steel balls acceleration she concludes that the collision between the foam rubber balls is an
