## Homework Statement

A box of mass 6.0kg is accelerated from rest by a force across the floor at a rate of 2.0m/s for 7.0s. Find the net work done on the box.

## Homework Equations

Work done = Force x distance

## The Attempt at a Solution

F = ma

F = 6 x 2 = 12N

i solved for final velocity i.e

V = u + at

= 0 + 2(7)

V = 14m/s.

i solved for distance

using v^2 = u^2 + 2as i.e

169 = 0 + 4s

s = 169/4

s = 49

we know that W = fd; thus

W = 12 x 49

W = 588J.

Please i just wanna know if my solution is correct. The answer in my text book is 590J. I'm assuming it was rounded up but i just want to be sure. Thanks for any help.
