## Homework Statement

Consider a Rocket in space, far removed from external gravitational influences, and suppose the engine starts up. As long as the engines are running, its instantaneous velocity v is a function of its mass. V is given by:

V = A + B log(D/m)

A, B, D are physical quantities, find the dimensions of A, B and D.

## Homework Equations

V = A + B log(D/m)

## The Attempt at a Solution

From here I will refer to dimensions as such: [], ex. [V] dimensions of velocity.

[V] = L/T

thus [A] = L/T

I need to still find the

**and [D]. I am not entirely sure here of how to approach. But would the dimensions of log be nothing, in other words [D] = M or mass.**

and thus

and thus

**= L/T as well. Or it this a stupid assumption to make?**
