Two Charged Balloons are near each other. One balloon has a charge of 4.3 microCoulombs. The other balloon has a charge of 7.1 microCoulombs. The balloons are placed 38 cm apart. What is the force
between the two balloons?

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
