    Thank you!

    This is what I got:
    QSteam=(.148Kg)(2260J)=2260J
    QIce=(1Kg)(335J)=335J

    So .148Kg+1Kg=1.48
    W=1.48(9.8)=14.5

    Thank you!

    So for Height at 2 seconds I got: s=19.6(2) + (-9.81)(2)^2=19.58

    Potential Energy at 1 Seconds= (.2)(9.8)(14.695)=28.8
    Potential Energy at 2 Seconds=(.2)(9.8)(19.58)-38.5
