**Momentum-Impulse Theorem Collision:**

If no external force, momentum always conserved.

2
**Is the kinetic energy conserved?**

Inelastic collision Completely inelastic collision: stick together

3
Elastic collision If v1i ,v2i is same direction

4
**Object sticks to together:**

1200-kg car moving at 2.5 m/s is struck in the rear by a 2600-kg truck moving at 6.2 m/s. If the vehicles stick together the collision, what is their speed immediately after colliding? (assume that external forces may be ignored). 2600 kg 1200 kg 6.2 m/s 2.5 m/s vf

5
Ballistic Pendulum In a ballistic pendulum, an object of mass m is fired with an initial speed v0 at the bob of a pendulum. The bob has a mass M, and is suspended by a rod of negligible mass. After the collision, the object and the bob stick together and swing to through an arc, eventually gaining a height h. Find h in terms of m, M, v0, and g

7
collision in 2D m1=950 kg m2=1300kg Completely Inelastic collision

**Elastic collision: Find the final velocity of the car? 135 kg 96 kg**

1.24 m/s 0 m/s Find the final velocity of the car?

Chapter 6. When objects collide their motion changes and this is the result of a concept called momentum. Momentum = mass x velocity p = mv kgm/s or Ns.
