**[SOLVED] Power Problem**

## Homework Statement

An initially stationary 2.9 kg object accelerates horizontally and uniformly to a speed of 14 m/s in 4.7 s. (a) In that 4.7 s interval, how much work is done on the object by the force accelerating it? What is the instantaneous power due to that force (b) at the end of the interval and (c) at the end of the first half of the interval?

## Homework Equations

## The Attempt at a Solution

Not really sure what's involved in this question. I need to find Power which is F*velocity but I don't know the force. Force = m*a. What I am given is the mass and speed is the velocity right? So I need to solve for a. Is this correct?
