To understand how to find the velocities of particles after a collision. There are two main types of collisions that you will study: elastic and perfectly inelastic. In an elastic collision, kinetic energy is conserved. In a perfectly inelastic collision, the particles stick together and thus retain the same velocity after the collision. There is actually a range of collision types, with elastic and perfectly inelastic at the extreme ends. These extreme cases are easier to solve than the in-between cases.
In this problem, we will look at one of these in-between cases after first working through some basic calculations related to elastic and perfectly inelastic collisions.
Let two particles of equal mass m collide. Particle 1 has initial velocity v, directed to the right, and particle 2 is initially stationary.
A) If the collision is elastic, what are the final velocities v_1 and v_2 of particles 1 and 2? Give the velocity v_1 of particle 1 followed by the velocity v_2 of particle 2, separated by a comma.
Express each velocity in terms of v.
B) Now suppose that the collision is perfectly inelastic. What are the velocities v_1 and v_2 of the two particles after the collision?
C) Give the velocity v_1 of particle 1 followed by the velocity v_2 of particle 2, separated by a comma. Express the velocities in terms of v.

8.29 two streams containing pyridine and acetic acid at 25°c are mixed and fed into a heat exchanger. due to the heat-of-mixing effect, it is desired to reduce the temperature after mixing to 25°c using a stream of chilled ethylene glycol as indicated in the diagram. calculate the mass flow rate of ethylene glycol needed. the heat capacity of ethylene glycol at these conditions is approximately 2.8 kj/(kg k), and the enthalpy change of mixing (δmixh) is given below.
