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
