1. Two objects are arranged on a level, frictionless table as shown. Two experiments are conducted
in which object A is launched toward the stationary block B. The initial speed of object A is the
same in both experiments; the direction is not. The initial and final velocities of object A in each
experiment are shown.
The mass of block B is four times that of object A. (m=4m)
