1. In the previous question the first collision was elastic and the second was inelastic. Is momentum conserved in each of these situations?
Prev. question : A steel ball collides with a steel wall and bounces off. A second steel ball with the same mass and velocity collides with a magnet and sticks to it. Which steel ball underwent the greater impulse? Why?
Homework Answers
In both Elastic and inelastic collision momentum of system will be conserved.
If no external force acts on system then momentum of system will be conserved.
in case of elastic collision kinetic energy of system is conserved while in case of inelastic collision kinetic energy of system is not conserved

Contrast and compare elastic and inelastic collisions.
Question 4 options:
Both elastic and inelastic collisions have conservation of
momentum if there are no outside forces. They are different in that
elastic collisions bounce and inelastic collisions stick, and
kinetic energy is conserved in inelastic collisions.
They are basically the same thing, except the units are
different.

Elastic Collision Question 8 A 2 kg ball initially at rest rolls down a 30-degree inclined plane from a height of 4 meters (assume kinetic and rolling friction are negligible). A 2 kg box initially at rest slides down a 30-degree directionless inclined plane from a height of 4 meters. How do the velocities of the ball and the box compare when they both reach the bottom of their respective inclined planes?...

1. You throw a ball purely horizontally through the air, it bounces off a wall and continues at about the same speed back towards you also purely horizontally (pretending gravity isn't a factor). Then can we say that the impulse delivered onto the ball from the collision with the wall is about double the momentum it had at the start? True False 2. The total momentum of a system subject to only internal forces (one that is isolated) is conserved....
