A mass m, attached to a spring with constant k, oscillates according to x(t) = Asin(wt), where w^2 = k/m. When x = A/2, what is the ratio of the kinetic energy to the total energy of the spring-mass system? (KE/Etot) A. 1/4 B. 3/4 C. 1 D. 1/2

Step 1
Step 1: Given x = A/2, we can substitute this value into the equation for kinetic energy: KE = 1/2 * m * w^2 * (A^2 - (A/2)^2) Show more…

Amass T is attached to a spring with constant k. It oscillates according to the equation Asin(wt), where w^2 = k/m. When x = A/2, what is the ratio of the kinetic energy (KE) to the total energy (Etot) of the spring-mass system?

An object is suspended from a spring whose mass is negligible compared to the object. The object is displaced a maximum distance A, and is observed to oscillate with a maximum kinetic energy K. The spring is then cut in half and the object is suspended from one of the halves. The object is then displaced a maximum distance of A/2, and the maximum kinetic energy is observed to be K'. The ratio K'/K is A) 1/2 B) 1/√2 C) 1 D) √2 E) 2

A 36-kg mass is placed on a horizontal frictionless surface and then connected to walls by two springs with spring constants $k_{1}=3 \mathrm{~N} / \mathrm{m}$ and $k_{2}=4 \mathrm{~N} / \mathrm{m},$ as shown in the figure. What is the period of oscillation for the $36-\mathrm{kg}$ mass if it is displaced slightly to one side? a) $11 \mathrm{~s}$ d) $20 \mathrm{~s}$ b) $14 \mathrm{~s}$ e) $32 \mathrm{~s}$ c) $17 \mathrm{~s}$ f) 38 s
