Problem 72

Two snowy peaks are at heights H 850 m and h 750 m above the valley between them. A ski run extends between the peaks, with a total length of 3.2 km and an average slope of 30# (Fig. 8-61). (a) A skier starts from rest at the top of the higher peak. At what speed will he arrive at the top of the lower peak if he coasts without using ski poles? Ignore friction. (b) Approximately what coefficient of kinetic friction between snow and skis would make him stop just at the top of the lower peak? h H Figure 8-61 72.

Step-by-Step Solution:
Step 1 of 3

Two models of community organization are common: Bottom­Up and Top­Down model. The V  H (V for Vegetation and H for herbivore) linkage suggests a bottom­up model, which postulates unidirectional influence from low and high tropic levels. In this case, the presence or absence of mineral nutrients (N) controls plant numbers, which control herbivore numbers, which then control the number of...
