Mass on a horz. spring

  1. Apr 15, 2009 #1
    A 53 gram mass is attached to a massless spring and allowed to oscillate around an equilibrium according to:
    y(t) = 1.2*sin( 3.1415*t ) where y is measured in meters and t in seconds

    (a) What is the spring constant in N/m ?

    (b) What is the total Mechanical Energy in the mass/spring system?

    (c) What is the maximum Kinetic Energy of the mass?

    (d) What is the maximum velocity of the mass in m/s ?
