Question

please help

Answer 1

impulse= change in momentum = (consider downward direction as positive) then mv-(-mv)
and v= rt(2gh)

Answer 2

i don't understand the thought process behind this..

Answer 3

we define impulse as F.dt = m.dv/dt .dt= m.dv => impulse= change in momentum

Answer 4

@m806texas , do you have an understanding of this calculus? If not, that's okay!

Answer 5

The way I see it, divu.mkr is right. Impulse is the change in momentum before and after the collision (for this question).

Answer 6

So, you'll want to know the velocity when it hits, to find its momentum then. And you'll want then see how that differs from the momentum after the collision (with 4.0 m/s).
