There are two planets. planet 1 is three times the mass of planet 2. however, a person standing on the surface of planet 2 experiences a force that is 12 times stronger than on planet 1. how is this possible? explain in terms of physics phenomena and terminology.

The slope of a good speed time indicates ? a. velocity b. acceleration c. direction d. speed

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
