Two snowy peaks are H = 790 m and h = 750 m above the valley between them. A ski run extends bewteen the peaks, with a total length of 3.1 km and an average slope of? = 30°. (a) A skier starts from rest on the higher peak.

The mass of a high speed train is 4.5*105kg, and it is traveling forward at a velocity of 8.3*101m/s. given that momentum equals mass times velocity, determine the values of m and n when the momentum of the train (in kg⋅m/s) is written in scientific
