[QUOTE="marsupial, post: 5523009, member: 599432"] [h2]Homework Statement [/h2] A block A of mass m traveling with speed v collides head-on with a stationary body B of mass 2m. The two bodies stick together. Calculate the impulse exerted by body B on body A during the collision. [h2]Homework Equations[/h2] ## J = p_{final} - p_{initial} ## ## p_{initial} = p_{final} ## [h2]The Attempt at a Solution[/h2] I am not sure if this is correct. First I considered the system of the two blocks to calculate v': mv + 0 = 3mv' -> v' = v/3 Then I calculated the initial and final momentum of block B on A using v' for final velocity: ## p_f - p_i = 2mv/3 - 0 = 2mv/3 ## But I don't feel confident in the answer.
