A 200 g mass is attached to a spring of spring constant k. The spring is compressed 15 cm from its equilibrium value. When released the mass reaches a speed of 5 m/s. What is the spring constant (in N/m)?

  • Physics -

    w*(amplitude) = maximum velocity
    Solve for w (in radians/second) and then use
    w = sqrt(k/m) to get k, the spring constant
    Amplitudes and velocities must be in meters and m/s. Mass must be in kg
