    Finding Energy Given Mass and Height

    I did U=(918kg)(9.81m/s^2)(13.8m) U= 124277 J This was not an accepted answer. I also converted kg to g and it was also incorrect.

    Finding Energy Given Mass and Height

    I've tried to set U=mgh and used 9.81 m/s^2 for g and that didn't work. Then I assumed that because the water is being pulled at a constant acceleration the force would be equal to the mass of the water; W=mh. That also did not work. Finally, I set mgh=1/2mv2 and solved for velocity to be 16.45...

    Finding Energy Given Mass and Height

    [b]1. It is claimed that large trees can evaporate as much as 918 kg of water per day. Evaporation takes place from the leaves. To get there, the water must be raised from the roots of the tree. Assuming that the water must rise an average of 13.8 m from the ground, how much energy must be...
