A 860g block of titanium metal has a volume of 200 cm3 and the density of 4.3g/cm^3. What would be the density of the block of titanium metal if the volume of the block was 500 cm3 and the mass of the
block was 2150g?

When the displacement of a mass on a spring is 12a the half of the amplitude, what fraction of the mechanical energy is kinetic energy? at what displacement, as a fraction of a, is the mechanical energy half kinetic and half potential?
