1. The problem statement, all variables and given/known data 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. 2. Relevant equations Impulse = F*delta(t) 3. 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'?
