When comparing data between two different groups, A.
only the average values of the data sets should be considered.
B.
the most frequently occurring values and the middle values should both be removed from the data sets.
C.
only the highest and lowest values of the data sets should be considered.
D.
the middles of the data sets and the spreads around them should both be considered.

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

Consider a system with two masses that are moving away from each other. why will the kinetic energy differ if the frame of reference is a stationary observer or one of the masses?
