What is the speed of a bobsled whose distance-time graph indicates that it traveled 120m in 27s? m/s

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

Another word for electromagnetic energy is a. heat b. force c. matter d. radiation

When you hold a rectangular object, how does the area of the side that is resting on your hand affect the pressure and the force that the object exerts?
