A1.0-kg block and a 2.0-kg block are pressed together on a horizontal frictionless surface with a compressed very light spring between them. (the blocks are not attached to the spring.) the blocks are then released and the spring uncompresses. immediately after the blocks lose contact with the spring, which statement below is true? a. the magnitude of the momentum of the heavier block will be greater than the magnitude of the momentum of the lighter block. b. the lighter block will have more kinetic energy than the heavier block. c. both blocks will both have the same amount of kinetic energy. d. both blocks will have equal speeds. e. the heavier block will have more kinetic energy than the lighter block.

Two steel balls, each of mass m, are welded to a light rod of length l and negligible mass and are initially at rest on a smooth horizontal surface. a horizontal force of magnitude f is suddenly applied to the rod as shown. determine (a) the instantaneous acceleration a of the mass center g and (b) the corresponding rate at which the angular velocity of the assembly about g is changing with time.
