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?

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?

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
>>7094050
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

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)

this is it here, OP >>7094231
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.

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
