## Homework Statement

Find final velocity.

Knowns:

m = 4kg

Initial v = 0 m/s

F = Asin(xt)

[itex]F = (2000N)(sin(\frac{1000π}{sec}*t)[/itex] (0sec ≤ x ≤ .001sec)

We need to find the impulse from a Force vs. Time graph.

There is a preface to this problem that says if we work out the Force function, we will see that the contact period is approximately 1 millisecond.

I don't see how that is possible. All I see here in regard to the Force function and the restriction is:

[itex]((0sec ≤ \frac{1000π}{sec} ≤ .001sec)[/itex] which makes no sense to me...

So is this question flawed from the beginning or am I completing not understanding what is being conveyed?

## Homework Equations

F* Δt = mΔt

## The Attempt at a Solution

Can not attempt yet. I don't understand the question to begin with.
