Temperature increase in water question

[muddahwhale]

1. A 50kg alumium block is dropped from a large height and hits a container of water at 150m/s. Assuming all the kinetic energy of the falling block goes into heating the 5kg water, what is the temperature increase of the water.

Homework Equations

Q=mc(change of t)
KE=.5m(v^) maybe?[/B]

The Attempt at a Solution

.5(50)(150^)=562500 Jules
562500= 5(4180)(change of t)
change of t= 26.9[/B]

Welcome to PF;
Do you not know the equation for kinetic energy? Then look it up.
Numbers are meaningless without units.
