A64.0-kg skier starts from rest at the top of a ski slope of height 62.0 m.
a)if frictional forces do -1.10×104 j of work on her as she descends, how fast is she going at the bottom of the slope?
take free fall acceleration to be g = 9.80 m/s^2.
b)now moving horizontally, the skier crosses a patch of soft snow, where the coefficient of friction is 0.18. if the patch is of width 70.0 m and the average force of air resistance on the skier is 160 n, how fast is she going after crossing the patch?
c)after crossing the patch of soft snow, the skier hits a snowdrift and penetrates a distance 3.0 m into it before coming to a stop. what is the average force exerted on her by the snowdrift as it stops her?

Use the frequency histogram to complete the following parts. ​(a) identify the class with the​ greatest, and the class with the​ least, relative frequency. ​(b) estimate the greatest and least relative frequencies. ​(c) describe any patterns with the data. female fibula lengths 30.5 31.5 32.5 33.5 34.5 35.5 36.5 37.5 38.5 39.5 0 0.05 0.1 0.15 0.2 0.25 length (in centimeters) relative frequency a histogram titled "female fibula lengths" has a horizontal axis labeled "length in centimeters" from 30.5 to 39.5 in increments of 1 and a vertical axis labeled "relative frequency" from 0 to 0.25 in increments of 0.05. the histogram contains vertical bars of width 1, where one vertical bar is centered over each of the horizontal axis tick marks. the approximate heights of the vertical bars are listed as follows, where the label is listed first and the approximate height is listed second: 30.5, 0.02; 31.5, 0.04; 32.5, 0.05; 33.5, 0.13; 34.5, 0.22; 35.5, 0.25; 36.5, 0.13; 37.5, 0.06; 38.5, 0.09; 39.5, 0.01. ​(a) the class with the greatest relative frequency is nothing to nothing centimeters. ​(type integers or decimals. do not round. use ascending​ order.)
