## Homework Statement

[/B]

Suppose I have a stationary object of mass 'm' and I want to apply a momentary force in the vertical direction so that it just reaches the height 'h'.

So how do I calculate the impulse required in this case?

Also how do I exactly define the delta(t) for the momentary force. shall I just take 1 sec.

## Homework Equations

Impulse = F*delta(t)

## The Attempt at a Solution

Since I need to accelerate the object, I think the work done = m(a+g)h

but I am also not sure how to exactly define this delta(t), shall I just use 1 second?

Also how to get the value of 'a'?
