2.b From the above figure, consider the collision of two masses m¡ and m2. Initially, m¡ moves to the right
with speed Vo then hits m2 (initially at rest).
Calculate the speed of the masses if the collision is inelastic.

respectively. Setup the equation for conservation of linear momentum and setup the equation for conser-
vation of energy.
