HELP!! mastering physics: 7.2: Conservation of Energy with Conservative Forces
I'm not understanding how conservative and nonconservative forcesinteract. I have a question assigned by my professor:A basket of negligible weight hangs from a vertical spring scale offorce constant1500 . If you suddenly put an adobebrick of mass3.00 in the basket, find the maximum distance thatthespring will stretch.There is a question that states (check all that apply) that aretrue: The spring is initially unstretched.After the brick has been placed in the basket,the spring is stretched.When the brick is first placed into...

Africtional force of magnitude = 22.0 acts on the toolbox as it slides. If the boxstarts = 4.25 from the lower edge of the roof, how fast will the toolbox be moving just as itreaches the edge of the roof? Assume...

To practice ProblemSolving Strategy 21.1 Conservation of energy in charge interactions.An alpha particle (), which is the same as a helium4 nucleus, is momentarily at rest in a region of space occupied by an electric field. The particle then begins tomove. Find the speed of the alpha particle after it has moved through a potential difference of 3.45×103 .The charge and the mass of an alpha particle are = 3.20×1019 and = 6.68×1027 , respectively.PROBLEMSOLVING STRATEGY Conservation of energy in...
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...

Learning Goal: To learn to apply the law ofconservation of energy to the analysis of harmonic oscillators.Systems in simple harmonic motion, or harmonicoscillators, obey the law of conservation of energy just likeall other systems do. Using energyconsiderations, one can analyzemany aspects of motion of the oscillator. Such an analysis can besimplified if one assumes that mechanical energy is notdissipated.In other words,,where is the total mechanical energy of the system, is the kinetic energy, and is the potential energy.As you know,...

Conservation of energy In the examples you have examined in this lab, as the coaster travels down the track its gravitational potential energy decreases, and its kinetic energy increases. At any point along the path of the coaster, the potential energy plus the kinetic energy add up to the same value. In the absence of friction and air resistance, we find that the total energy (kinetic plus potential) stays the same. For this reason, physicists call the total energy a...
