Question About A Simple Formula

[getfirefox]

Homework Statement

Since velocity = distance / time, the units of velocity are metres / seconds or ms^-1. Use the equations (below) to show that the unit of work done can be written as kg.m².s^-2.

acceleration = change in velocity / time
force = mass X acceleration
work done = force X distance

It's only a question about the "kind" of units.

Just show through substitution how the units for expressing work are
Mass*distance*distance over time*time
