Can any real collision ever be truly perfectly elastic? Why or why not? (You should think about this in two ways: first consider what effects of the environment surrounding the collision might have on energy and momentum conservation; second, consider the objects themselves – how must an object react to a collision in order to be considered "perfect"?).

A 1-kg ball moving at a velocity of 12 m/s collides head-on with a 2-kg ball moving at 24 m/s in the opposite direction. Calculate the velocity of each ball after collision If (a) e=2/3, (b) the balls stick together, and (c) the collision is perfectly elastic.
Is the following statement true? If not, why? Within the system, both the momentum and kinetic energy are conserved during each of the collisions ( spring-loaded elastic, hoop spring, and putty collisions).
distinguish elastic collisions from inelastic ones. are momentum and kinetic energy conserved in both types of collisions? why or why not?
a) Show that in in-elastic collision, in which K.E is conservative and momentum is not. Why? b) If you are stationary on ground and then you take a step forward. Before the step momentum was zero, but afterward you have some momentum. Is this a violation of law of conservation of momentum?
Question 7: A block of mass of 2m comes with initial speed vo and collides with a system of two particles connected by a spring of spring constant k elastically on a frictionless horizontal table, each having mass of m as shown in Figure 5. Find the maximum amount of the compression of the spring. 2m k m m Figure 5 Repeat the previous question if the collision is perfectly inelastic.
There is a large crater in Arizona called Meteor Crater. It is estimated that it was formed about 20,000 years ago by a meteorite that had a mass of about 5 x 10^10 kg and was traveling at a speed of 7.5 km/sec. How fast could this meteorite have hit the Earth (whose mass is 6 x 10^24 kg) if we assume a head-on collision?
Two balls (which we will label ball 1 and ball 2) undergo a perfectly elastic head-on collision, with ball 2 initially at rest. Suppose the incoming ball (ball 1) has a speed of 200 m/s. Assume all motion is one-dimensional and ignore friction and drag. (a.) Write out algebraic expression for both the Law of Conservation of Momentum and the Law of Conservation of Energy as they apply for this isolated system. (That is, for this part of the problem I want you to write the Conservation of Momentum equation and the Conservation of Energy equation for this system and plug in any known zero values but do not plug in any other numbers.) For the moment, leave the masses of the balls (m1 and m2) as algebraic variables (as I am not giving you numerical values for the masses just yet). (b.) We want to compute the final speeds (v1f and v2f) and directions (±x-direction, since the motion is assumed to be 1 dimensional) of the balls. We could use our conservation laws from part (a.) together to…
Assume two objects that collide with one another are both included in the system being observed. (a) If the motion is restricted to being along the x-direction (one-dimensional motion), then what equation must be true? (In other words, what equation applies to all 1-D collisions?) (b) Furthermore, if the two objects stick together after the collision, then what additional equation must be true? (c) What is the term for this type of collision? (d) Give an example of a reverse version of this type of collision.

Describe the difference between elastic and inelastic collisions in terms of energy.
Two identical pool balls are shot directly at one another at the same speed. Describe the ball'smotions after they collide, assuming that frictional forces may be neglected and the collisionis completely elastic. (Answer in no more than 3 sentences)
In this problem we will consider the collision of two cars initially moving at right angles. We assume that after the collision the cars stick together and travel off as a single unit. The collision is therefore completely inelastic Two cars of masses my and me collide at an intersection. Before the collision, car 1 was traveling eastward at a speed of v1, and car 2 was traveling northward at a speed of v. (Figure 1)After the collision, the two cars stick together and travel off in the direction shown.
