Hey guys, I need to know this: How big the acceleration needs

>>7694421
boooooooring

Vyloucen ze souteze.

Taky to ted resime :D Fakt jsem necekal ze tohle nekdo postne na 4chan
Fakt ses pica vole xD

Ok, we have 1 variable.

Thats not enough.

If we can get more variables, then a solution can be found

>>7694433
Its literally just this. No more informations given.

>>7694427
Haha. gr8 b8 m8

Kluci, nemyslel jsem si, že budete podvádět, docela mě to zklamalo, ne?

Zdeněk Polák LEL nice fake bruh.

stfu, newfag

How about the weight of the box?

You mean how much acceleration is needed in the up-ramp direction to counteract gravity on a frictionless slope? Just sin(20)*g

Didnt expect you to post this competition on 4chan bro:D You fucking killed me LOL

>>7694462
To víš.

thx m8

OP here, tak z jakejch týmu jste?

MRGAITS

>>7694421
any acceleration and µ = tan(20)

Actually the acceleration needs to be 0 and then the cube won't slip :^)

cos(a)^2*g

>>7694421
>acceleration
>prevent that block to slip down

pick one

g * cos(20)
