Chapter 7, Problem 47P

(a)

To determine

The final velocity of the blocks when a $4.0\text{ kg}$ block moving at $2.0\text{ m/s}$ west on a frictionless surface collides totally in-elastically with a second $1.0\text{ kg}$ block travelling east at $\text{3}\text{.0 m/s}$

(b)

To determine

The kinetic energy of each block before and after collision when a $4.0\text{ kg}$ block moving at $2.0\text{ m/s}$ west on a frictionless surface collides totally in-elastically with a second $1.0\text{ kg}$ block travelling east at $\text{3}\text{.0 m/s}$.

(c)

To determine

The difference of kinetic energy in the process when a $4.0\text{ kg}$ block, moving at $2.0\text{ m/s}$ west on a frictionless surface collides totally inelastically with a second $1.0\text{ kg}$ block travelling east at $\text{3}\text{.0 m/s}$.
