The black market sold Einstein a gun that is able to launch clumps of cookie dough. By accident einstein launches two clumps of cookie dough back to back vertically into the air. Launch speed was equivalent to 40m/s and time between launches = 5.5s. The cookie doughs collide and clump into 1 massive clump in the air and come back and clogg the gun. At what speed does the big clump enter the gun assuming both clumps were in mass.
