help with some physics problems?
1) Collectible coins are sometimes plated with gold to enhance their beauty and value. Consider a commemorative quarter-dollar advertised for sale at $4.98. It has a diameter of 20.4 mm, a thickness of 1.78 mm, and is completely covered with a layer of pure gold 0.145 ?m thick. The volume of the plating is equal to the thickness of the layer times the area to which it is applied. The patterns on the faces of the coin and the grooves on its edge have a negligible effect on its area. Assume the price of gold is $10.0 per gram. Find the cost of the gold added to the coin.
2)A highway curve forms a section of a circle. A car goes around the curve. Its dashboard compass shows that the car is initially heading due east. After it travels 840 m, it is heading 30.5? south of east. Find the radius of curvature of its path. Suggestion: Use s = r ? where ? is in radians.
appreciate any help at all in understanding these. thanks
For the first one you need the density of gold, and the surface area of the coin: (2*pi*(10.2mm)^2) + (pi*20.4mm*1.78mm). By the way the actual price of gold is well over $30.00 per gram.
