A solid metal sphere has a radius of 3.39 cm c m and a mass of 1.877 kg k g . What is the density of the metal in g/cm3 g / c m 3 ? (The volume of sphere is V=43πr3 V = 4 3 π r 3 .)
Homework Answers
Mass of sphere = 1.877kg = 1.877×1000g = 1877g
Volume of sphere = 4/3 π.r3 = 4/3 × 22/7 × (3.39cm)3
= 163.1878cm3
Density of metal = mass of sphere /volume of sphere
= 1877g/163.1878cm3
= 11.50 g/cm3
= 11.5 g/cm3. (Answer)

A small solid porcelain sphere, with a mass m and radius r, is placed on the inclined section of the metal track shown below, such that its lowest point is at a height h above the bottom of the loop. The sphere is then released from rest, and it rolls on the track without slipping. In your analysis, use the approximation that the radius r of the sphere is much smaller than both the radius R of the loop and...
