A0.25 kg ball is dropped from a 30 meter building. at the same time, a 2 kg ball is thrown downward with a 50 n force. neglecting air resistance and after it is thrown, the ball will have an acceleration (a) equal to 8 times that of the dropped ball. (b) equal to 1/8 of that of the dropped ball. (c) equal to that of the dropped ball. (d) always larger than, but not always 8 times larger than, that of the dropped ball. (e) always smaller than, but not always 8 times smaller than, that of the dropped ball.

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
