At the top of a pole vault, an athlete actually can do work pushing on the pole before releasing it. suppose the pushing force that the pole exerts back on the athlete is given by f(x) = (140 n/m )x - (190 n/m2 )x2 acting over a distance of 0.19 m .how much work is done on the athlete?

The process of predicting values that extend beyond the range of data points is called absolute value extrapolation interpolation prediction for any given: )
