Find the kinetic energy k of the block at the moment labeled b.


MasteringPhysics: PS 12 Energy of Harmonic Oscilla Find the kinetic energy K of the block at the moment labeled B. (Express answer in terms of k and A)

Answer

We know that total energy TE = 0.5kA^2 Spring energy SPE = 0.5k (A/2)^2 kinetic energy K = TE -SPE = 0.5 kA^2 – 0.125 kA^2

= 0.375 kA^2 Answer
