In a food fight, two blobs of Jell-O collide and stick together. Initially, the 35.0 g blob was traveling at 9.60m/s to the right, and the 85.0 g blob was moving at 8.4 m/s to the left. What is the velocity of the new, larger blob?

Awater slide of length l has a vertical drop of h. abby's mass is m. an average friction force of magnitude f opposes her motion. she starts down the slide at initial speed vi. use work-energy ideas to develop an expression for her speed at the bottom of the slide. then evaluate your result using unit analysis and limiting case analysis. express your answer in terms of the variables h, m, l, vi, f and appropriate constants. vf v f
