## Homework Statement

Ive got another question that I think I might have failed at.

A dog weighing 250 kg jumps into an empty boat by the dock at a speed of 5m/s causing the boat to move away form the shore at 1.75m/s. Find the amount of kinetic energy dissipated.

## Homework Equations

KE=1/2*m*v^2

## The Attempt at a Solution

Before

KE=1/2*m*v^2

KE=(.5)(250kg)(5.0m/s)^2

KE(1)=3125

and after

KE=1/2*m*v^2

KE=(.5)(250)(1.75m/s)^2

KE(2)=382.813

KE1-KE2=2742.19

KE dissipated = 2742

So am I right?
