An inelastic collision is one in which: kinetic energy before the collision equals kinetic energy after the collision.

kinetic energy after the collision is zero.

kinetic energy before the collision is less than kinetic energy after the collision.

kinetic energy before the collision is greater than kinetic energy after the collision.

Who was the first scientist to measure speed as distance over time?

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
