SHOW WORK A 2 kg basketball is being held at rest 1 m above the ground.
a. How much potential energy does the basketball have?
b. How much kinetic energy does the basketball have?
c. How much total mechanical energy does the basketball have?​

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
