Solve the all parts of given question:
Question: A toboggan approaches a snowy hill moving at 14.7m/s. The coefficients of static and kinetic friction between the snow and the toboggan are 0.450 and 0.350, respectively, and the hill slopes upward at 42.0 degrees above the horizontal.
Part I: Find the acceleration of the toboggan as it is going up the hill. Assume +x axis directed up the hill.
Part II: Find the acceleration of the toboggan after it has reached its highest point and is sliding down the hill. Assume +x axis directed up the hill.
Please give a full detailed explanation of solution.
A metal object is suspended from a spring scale. The scale reads 920 N when the object is suspended in air and 750 N when the object is completely submerged in water. Discover the volume of the object. Discover the density of the metal.
