Clothes dryer uses about 7 amps of current from a 240 volt line. how much power does it use?

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

Mechanical energy is when the amount of kinetic and potential energies added together remains the same. conserved created lost
