If two balloons are tied to a chair and are 0.1 m apart. What is the electrostatic force between those two balloons, if each balloon carries a charge of 4.6 µC (4.6 × 10-6 C, or 0.0000046 C).

Rocío strikes a 0.058-kg golf ball with a force of 272n and gives it a velocity of 62.0m/s. how long was ricío club in contact with the ball?

An incident ray through the focal point of a spherical mirror will: reflect through the center of curvature. reflect back through the focal point. reflect parallel to the principle axis. reflect the same direction as the incident ray.

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
