Help me with my homework
Das boot! toot toot
Nigga I can barely read English, fuck is this shitg
zing fraeng heil schwein gott
nigga are u like 16 years old
the cube is falling on a wedge
cube has mass m
wedge has mass M
wedge has tilt angle (alpha)
everything is frictionless
question is
how fast is the cube moving after it falls and slides down the slope?
no
how old are you
Schau einfach in die formelsammlung mein sohn
I happen to be an idiot on this topic but if you want to calculate speed would you not need something that lets you know the distance or time spent moving? Or is this a trick question because everything has no friction?
can't help you with that
t. realschulabschluss
honestly, I think that the mass of the wedge isn't even needed to solve this question
Heil Hitler Landsmänner, das Ü ersetzt nun offiziell :) und :D, Befehl von Führer
So you know the answer?
I'm attending Wirtschaftsgymnasium and what is this? uwu
that cube gon slide down
the wedge is not stationary
it also slides to the right
if you have the energy and the mass you can know the speed
>the wedge is not stationary
what?
how retarded
this
where in the problem does it specify which direction the wedge is moving?
But you don't have the energy, right? So how do you find the energy of a closed (I assume) system just by knowing the mass of its components?
this is a university problem, not high school homework
if you know the potential energy of the cube, then that must be equal to the kinetic energy of the cube and the wedge after the cube has finished sliding down the wedge
since you know the mass of the cube, and the potential energy, you can solve for velocity
homework of any kind is retarded, i never did it
So, wait, is h the height of the slope or did it fall from the air?
Potential energy (mgh) at top is max and at the end of the slide is 0, while kinetic energy(mv^2/2) is 0 at the start and max at the end, and since there is 0 friction loss we can say that they are equal.
mgh = (mv^2)/2
and v=+sqrt(2gh)
fuck off underaged fag
lol retard
newton's 3rd law
my wife cirno is so cute
oh my goodness
this is it here, OP but you can't solve the equation when you have exactly zero numbers to go off of. So unless you're hiding something it is not possible to calculate how far it will go.
retarded fat nigger do you even abstract nigger
Okay then Mr. Goldstein, if you're gonna stand on a pedestal and act smart, then solve it.
Based
if friction=0 then the cube will not affect the wedge it's irrelevant that the wedge is not stationary if the initial speeds are the same
so Ek0+U0=Ek1
do you even high school bro
also if friction wasn't 0 you would've solved this by calculating the work done by the cube and by the wedge and you could've expressed the speed of the wedge after the cube is done falling
There is no hight given
