A spring, (spring constant of 400 N/m) is displaced .75 m from its equilibrium position. An 8-kg mass is connected to the spring and it is allowed to oscillate horizontally with Simple Harmonic Motion. What is the Kinetic Energy of the mass?

  • Physics - ,

    A=0.75 m, m=8 kg, k= 400 N/m
    ω=sqrt(k/m) = …
    x=Acosωt
    v= - Aωsinωt
    v(max) = Aω
    KE=mv²/2 =0.5m A²ω²sinωt
    KE(max) = 0.5m A²ω²
