So I'm going to Japan later this month. I'll be staying in Ikebukuro, Tokyo; and later in Tennoji, Osaka. Anyone know of anything interesting to do?

I'll probably visit C77 while I'm there.

Just take any moe pose that's been posted in a million different varieties on Danbooru and it's probably used in it. Those three are the ones used in the game that I played, but I'm pretty sure they mix it up.

Hello there physicists, I have a question;

A 0.50 kg wooden block is dropped from a height of 15.0 m. At what height must a 005.0 kg bullet traveling upward strike the block in order to momentarily stop its fall? Assume that the time required for the bullet to come to rest is in the block is negligibly short and that the bullet travels with a speed of 320 m/s immediately before striking the block.

Does anybody know the solution?

I don't like my answer because it does not seem right. I have 14.995 m.

It is still mathematically possible, at least, for the formula associated with inelastic collisions for the final velocity of the two objects to be a zero vector. It is clear that we started out with more kinetic energy prior to impact than after, since before, we had 0.5*m_bullet*|v_bullet|^2 + 0.5*m_block*|m_block|^2 and afterwards, we have, as you said, 0. However, kinetic energies cannot "cancel out" the way forces and fields do. What occurred was a dissipation of kinetic energy as work deforming the block and heat emitted due to friction. I submit that this does not tell us what the relationship between the kinetic energy of each object is, but assuming a completely elastic collision (which this problem describes), we can set the right side of the respective momentum equation to a zero vector and proceed from there.

But then, like I said, I think I went wrong somewhere with my solution.

I argue that the kinetic energy of the brick and the bullet have to be equal to one another or otherwise they wouldn't cancel each others motion at the collision.

this leads me to believe that just before the moment of impact the bullet would have Ek=0.5*0.005*320^2=256J of energy. the brick needs to pick up speed while falling until it's fast enough to have equal kinetic energy.

v=sqrt(256/(0.5*5))=10.12 m/s(rounded)
v=gt so 10.12/9.81=1.03 s (rounded)

after 1.03 seconds the brick goes fast enough.
d=0.5gt^2 so d=0.5*9.81*1.03^3=5.20 meter (rounded)

so, the height is around 15-5.20=9.80 meters

>> No.10573   [Delete]   [Edit]

Forgot to submit my comment earlier.

Momentum is always conserved in a system with no outside work done to it; kinetic energy, however, is not conserved in an inelastic collision.

Why exactly, then, would the inelastic collision equation not apply?

>> No.10575   [Delete]   [Edit]

if it were an inelastic collision the bullet wouldn't dig inside the brick and get stuck there, but the 2 would bounce right off like 2 approaching snooker balls. consider newtons cradle: http://upload.wikimedia.org/wikipedia/commons/d/d3/Newtons_cradle_animation_book_2.gif)
only in this case would momentum be preserved. a true completely inelastic collision however does not exist in real life.
