## Homework Statement

A block starts at rest. A hand pushes the block with 6.1 N to the right across a rough surface, with 1.5 N of friction. if the block moves 1.6 m horizontally determine the following (a) work done by hand (b) work done by friction (c) the amount of thermal energy created (d) the amount of kinetic energy created?

## Homework Equations

W= F x D

work by force = F x D

## The Attempt at a Solution

6.1 x 1.6 = 9.76

1.5 x 1.6 = -2.4[/B]
