What kind of collision does conserve momentum? What kind of collision does not conserve mechanical energy?
What kind of collision does conserve momentum? What kind of collision does not conserve mechanical energy?
The game of pool does not conserve mechanical or kinetic energy. In this case, a 0.3kg cue ball ap- proaches a 0.2kg 8 ball at 3m/sî and strikes it, send- ing the two off on the given angles 0 and path of eight ball . 0-28 0.2kg fo.3ka 3 ms. a) Draw an interaction diagram with a defined sys- tem of the contact, and determine what is con- served in that system. path of cue ball ..0 = 24 b)...
What is the total momentum and total energy? total momentum total energy before collision 0) 6 m/s 9 m/s 8kg
1) Under what circumstances is mechanical energy conserved? Under what circumstances is momentum conserved? How is this different than the criteria for conservation of mechanical energy?
C What is conserved in the following cases (linear momentum, angular momentum about an axis, mechanical energy, tionle kinetic energy, none of these)? There may be more than one conserved quantity. For this question, you do not have to show your reasoning (a) Two masses are released from rest, from the positions shown in the figure, in a frictionless hemispherical bowl. The masses collide and stick together. Note that the circular motion is characterized simultaneously by the linear and angular...
State the laws of conservation of linear momentum and mechanical energy.
2. In an elastic collision, energy is not conserved. Where does it go? A) It is transformed into heat and also used to deform colliding objects. B) It is converted into potential energy. C) It is transformed into momentum such that momentum is conserved. D) All of the above. E) None of the above.
PROBLEM 2 (5 points). Momentum and Mechanical Energy conservation A rifle bullet with mass 150 g strikes and embeds itself in a block with mass 1000 g that rests on a frictionless, horizontal surface and is attached to a coil spring. The initial velocity of the bullet was 700 m/s. The impact compresses the springy a distance x. The spring constant is 550 N/m. The spring is ideal. a) Find the magnitude of the block's velocity (with the bullet stuck...
For each of the following situations, identify which of mechanical energy, kinetic energy, and momentum is/are conserved. Your answer may contain anywhere from zero to all three of these options. (pt each; pt bonus for getting 5 or more correct; another point bonus for getting all 7 correct) (a) A rock slides down a frictionless ski jump ramp, flies off the ramp, bounces off a vertical spring, and then is about to land on the ground. (b) At a July...
If you don't conserve angular momentum you can't make any transitions! How can you make any transitions if you don't conserve angular momentum?' (a) (2 points) If an electron makes a transition with Deltal = 1 and Deltaj = 0 (i.e. magnitude of the total angular momentum doesn't change but the orbital angular momentum of the electron does change), how is this possible? How can a system absorb the angular momentum of the photon without the magnitude of its angular...
