Explain the process through which kinetic energy is lost in an inelastic collision.
 
  What will be an ideal response?

Question 2

A sphere is constructed of two concentric pieces. The inner part is a solid sphere of radius 10.0 cm made of a material with density 4000 kg/m3.
 
  The outer part is a spherical shell with inner radius 10.0 cm and outer radius 20.0 cm. The outer shell has a density 9000 kg/m3.
  (a) What is the mass of this sphere?
  (b) What is the average density of this sphere?

Answer to Question 1

Some of the initial kinetic energy is transformed into other types of energy, such as thermal or potential energy, so the total kinetic energy after the collision is less than the total kinetic energy before the collision.

Answer to Question 2

(a) 281 kg
(b) 8.38  103 kg/m3
