1. For a ball falling straight down, sketch a graph of kinetic energy vs. time, and a graph of potential energy vs. time. Assume that zero potential energy is at the floor. 2. Sketch a graph of the total energy vs. time for the ball. 3. What is Hooke’s law? What measurements would you make so you could construct a graph that would allow you to use Hooke’s law to find the spring constant. 4. In terms of force, when...

Now let’s use the concept of elastic potential energy to solve a problem involving a spring. A glider with mass m=0.200kg sits on a frictionless horizontal air track, connected to a spring of negligible mass with force constant k=5.00N/m. You pull on the glider, stretching the spring 0.100 m, and then release it with no initial velocity. The glider begins to move back toward its equilibrium position (x=0). What is its speed when x=0.0800m? Part a: What is the value...
NEED HELP with...Energy of Harmonic Oscillators
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,...

Question 2: A particle of mass m moves in a potential energy U(x) that is zero forェ* 0 and is-oo at r-0. This is am attractive delta function, very odd. Do not worry about the physical meaning of the potential, just roll with it for now. The system is described by the wave function Afor <0 where a is a real, positive constant with dimensions of 1/Length, and A is the normalization constant, treat it as a unknown complex-number for...

А D z Problem 3. Work done by gravity and change in gravitational potential energy In problem the box was moving in a horizontal direction, and therefore no work was done by gravity. Here, we will analyze a situation where the force of gravity has some component that points along the direction of the displacement, and therefore there is non-zero work done by gravity on the system of interest Consider a box of mass 10 kg, initially at rest, which...
