  1. Momentum-Impulse TheoremCollision: 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. vf 6.2 m/s 2.5 m/s 2600 kg 1200 kg 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).

  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

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

  7. 135 kg 135 kg 96 kg 96 kg 1.24 m/s 0 m/s Elastic collision: Find the final velocity of the car?
