1. Since work equals force times distance(W = F*d), and the force or weights and distance were equal, the amount of work was also equal. 2. We can use the horsepower(hp) Eq to compare their power outputs: hp = f*d / 550t = f*d / 550*30, hp = f*d / 16500 = 6.06x10^(-5)*fd. hp...

since AF is the perpendicular bisector of BD, therefore BF=FD. since DF=FD=13, BF=13 now, if you draw this figure, you will see that you form a right triangle (AFD) when you connect A and D,, connecting A and B, you form another right triangle,, since they share a common ...
