Deriving net force from mass, velocity, and time

[elasticities]

Homework Statement

Derive an equation for the constant net force acting on an object in terms of the object's mass, its initial velocity, final velocity and time interval during which net force is applied.

Homework Equations

Fnet=ma
a=v2-v1/t

The Attempt at a Solution

Fnet=mass(v2-v1/t)

Is this right? Or are you supposed to simplify it more?
