In fig. 8.11, determine the character of the collision. Themasses of the blocks, and the velocities before and after aregiven. The collision is:

A) completely inelastic

B) partially inelastic

C) perfectly elastic

D) characterized by an increase in kinetic energy

E) not possible because momentum is not conserved.

Two identical objects 1 and 2, each having a mass of 1kg, movetoward one another at the same speed 1m/s, as shown in thefigure



The objects collide.

a.) If the collision is elastic, find the velocities (magnitude& direction) of each object after the collision

b.) If the objects stick together (i.e. the collision isinelastic), calculate their common speed after the collision

Let two objects of equal mass collide. Object 1 has initialvelocity , directed to the right, and object 2 is initiallystationary.
1. If the collision is perfectly elastic, what are the finalvelocities and of objects 1 and 2?
2. Now suppose that the collision is perfectly inelastic. What arethe velocities and of the two objects after the collision?
3.
Now assume that the mass of object 1 is , while the mass of object2 remains . If the collision is elastic, what are the finalvelocities and of objects 1 and 2?
4. Let the mass of object 1 be and the mass of object 2 be . If thecollision is perfectly inelastic, what are the velocities of thetwo objects after the collision?
