Spring Constants & Periods By varying the mass placed on a spring, the period of oscillation...
(a) Find the period of oscillation for a spring-mass system where the spring constant (k) is 24 N/m and the mass (m) is 6 kg. (b) Write an equation for x(t) if the spring is stretched to an amplitude of 10 cm from its equilibrium position x = 0 at t = 0. (c) Write an equation for the following initial conditions: at t = 0, the mass is at x = 0 and has a velocity of +3 cm/s.
Steven says that the period T of an object on a spring is depends on the mass m of the object and the spring constant k of the spring in the following way: T=2π(m/k). Jessica says that the period T of an object on a spring is depends on the mass m of the object and the spring constant k of the spring in the following way: T=2πsqrt(m/k). -The various combinations of masses and spring constants moves on a low...
You perform the Simple Harmonic Motion experiment and create a plot of Period-Squared vs. Mass. You add a linear fit and find the following equation of the line: y=9.52x-0.067 What is the spring constant, k (in N/m or kg/s2)?
Use matlab a) Create a simulated data set b) Create a set of plots to determine the best transformation to linearize the data c) Fit a first order polynomial (y mx + b) to the linearized data to find the constants m and b d) Reconstruct the original equation from m and b in the linear fitted polynomial e) Plot the fitted equation. Radioactive decay is modeled by the equation: rt where A the amount of mass as a function...

a can be skipped Consider the following second-order ODE representing a spring-mass-damper system for zero initial conditions (forced response): 2x + 2x + x=u, x(0) = 0, *(0) = 0 where u is the Unit Step Function (of magnitude 1). a. Use MATLAB to obtain an analytical solution x(t) for the differential equation, using the Laplace Transforms approach (do not use DSOLVE). Obtain the analytical expression for x(t). Also obtain a plot of .x(t) (for a simulation of 14 seconds)...
mass weighing W pounds stretches a spring 7 foot and stretches a different spring foot. The two springs are attached in series and the mass is then attached to the double spring as shown in the figure below. (a) A rigid suppont that the motion is free and that there is no damping force present. Determine the equation of motion if the mass is initially released at a point 1 foot below the equlbrium postion with a downward velocity of...

For the red and blue masses in the simulation, perform experiments to determine their mass. Show your...
Place your answers on the templates provided. Show your work. Directions: 1. A doctor knows that muscle mass decreases with age. To help him understand this relationship in women, the doctor selected women beginning with age 40 and ending with age 80. The data is given in the table below. x is age, y is a measure of muscle mass (the higher the measure, the more muscle mass). Use your calculator to make a scatter plot that shows how age...
Friction Lab Questions (Part 2 Only) Part 1. The friction force is equal to mg where m is the mass attached to block slides at constant speed. The normal force is equal to Mg where M is block plus added masses. Thus, equation ( 1 ) becomes mg-Afg or m fat . Thus, need to multiply the masses by g to get weight and we can just graph m on the y the x-axis. The slope of the line will...
