Question

Definition Definition Angle at which a point rotates around a specific axis or center in a given direction. Angular displacement is a vector quantity and has both magnitude and direction. The angle built by an object from its rest point to endpoint created by rotational motion is known as angular displacement. Angular displacement is denoted by θ, and the S.I. unit of angular displacement is radian or rad.

If you did the previous question right, you hopefully got an expression for yo. You may notice that you can simplify the differential equation a little bit: d'y k (y – yo) dt2 т The parameter yo now plays the roll of the "relaxed length". A better term may be "equilibrium value for y". But mathematically, it's identical to a relaxed length with the spring as the only force. We continue using this equation: y(t) = Y0 + A cos(wt + y) Now, solve for A (in cm) with these parameters. Again, if you need more information, enter -100000. The parameters are: •m = 200 grams • Yo = (equilibrium value) = 40 cm • k = (spring constant) = 0.03 N/cm

Problems 5 & 6 refer to the mass-spring oscillator depicted in the figure on the right. The block has a mass of 350 g, and is attached to a spring with a spring constant of k pushed 20 cm to left from C, its equilibrium position, before being released and allowed to move horizon- tally on a frictionless surface. . Ax = 20 cm 45 N. The mass is initially m A B DE 5. What is the frequency of oscillation for the block? A. 0.13 Hz В. 0.35 Hz С. 1.8 Hz D. 7.8 Hz 5. 6. What is the speed of the block as it passes point B? A. 0.50 m/s В. 1.0 m/s C. 1.5 m/s D. 2.0 m/s 6.

Our unforced spring mass model is mx00 + βx0 + kx = 0 with m, β, k >0. We know physically that our spring will eventually come to rest nomatter the initial conditions or the values of m, β, or k. If our modelis a good model, all solutions x(t) should approach 0 as t → ∞. Foreach of the three cases below, explain how we know that both rootsr1,2 =−β ± Sqrt(β^2 − 4km)/2mwill lead to solutions that exhibit exponentialdecay.(a) β^2 − 4km > 0. (b) β^2 − 4km =0. (c) β^2 − 4km >= 0.
