What is the relationship between saying conserved quantity and inelastic collision of two objects, as if the latter circumscribes the result, conserved quantity, if at all? Momentum, kinetic energy, neither, both.  I don’t understand the relevant concepts.

A 75 kg person standing on a frictionless floor fires two 100 gram bullets at 500 m/s (parallel to the ground) one right after the other out of a 3 kg gun; use conservation of momentum to calculate the recoil speed at which the person slides backwards (show all the math steps in your derivation):

Use the concepts of this chapter to describe what would happen if you fire a gun that has bullet ten times as massive as the gun. (Has to do with the conservation of momentum)

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).

Let's assume a perfectly elastic collision between a golf club (mass of 250 gr) and a golf ball (mass of 46 gr). If the club hits the ball at a speed of 45 m/sec what will be the speed of the ball after the impact?  What happens if the mass of the club is doubled?

ball 1 (1kg) moves at 1m/s strikes stationary ball 2 (1kg). Ball 1 stops, ball 2 moves away at 1m/s. Is momentum,KE, or both coversed? Explain. Is this elasic collision or inelastic collison?

I. A lump of clay (m = 3.00 kg) is thrown towards a wall at speed v = 3.00 m/s. The lump sticks to the wall. (a) What kind of collision is it? Is momentum conserved during this collision? Why or why not? (b) Calculate the impulse imparted on the lump by the wall. (c) Calculate percent of initial kinetic energy lost during this collision. II. Same lump is thrown towards the same wall, but this time it bounces off the wall at speed of 3.00 m/s. (a) What kind of collision is it? Is momentum conserved during this collision? Why or why not? (b) Calculate the impulse imparted on the lump by the wall. (c) Calculate percent of initial kinetic energy lost during this collision. III. Same lump is thrown towards the same wall, but this time it bounces off the wall at speed of 2.00 m/s. (a) What kind of collision is it? Is momentum conserved during this collision? Why or why not? (b) Calculate the impulse imparted on the lump by the wall. (c) Calculate percent of initial kinetic energy lost during…

Was momentum conserved in these collisions?  If not, provide a brief explanation.

In a system with two moving objects, when a collision occurs between the objects: the total kinetic energy is always conserved. the total momentum is always conserved. neither the kinetic energy nor the momentum is conserved. the total kinetic energy and total momentum are always conserved.

(a) After J. J. Thompson experimentally discovered the existence of electrons in 1897, he went on to propose the plum pudding model of matter. What was the plum pudding model? What did Ernest Rutherford conclude about the structure of matter based on his experimental results from bombarding gold foil with alpha particles? (b) What was the proposed atomic model of matter put forward by Rutherford? Theoretically what was the problem with his proposed model of the atom? (c) What was the modification made by Niels Bohr to Rutherford's model, i.e., what were the assumptions that Bohr made for his version of the atomic model of matter? (d) What observational phenomena was Bohr's proposed model able to explain? How did his model explain these phenomena? (e) Draw an energy level diagram with one representative transition to support your answer to part (d).
