also is there a different formula to use for this when its on an angle, i know momentum before has to equal momentum after as does kinetic energy, mind you its not asking for kinetic, only speed, the balls are the same size so in the momentum formula we can get rid of the mass?, and its obvious...

The Attempt at a Solution
is this just as simple as the momentum formula before and after, or am I forgetting...
actually, it seems like the answer becomes 2.75kg which would mean in the direction of M1 which wouldnt be what we wanted so actually we could get it moving in the right direction by adding 2.8kg of weight to m2
does that make more sense then i can just figure out the acceleration of the...
so i do all that and if they equal the same the system wont move correct? so i know Fn is 417.87 for block 1 and i know the right force is 343.35N so to find left components i can go Fleft + Ff so 194.85 +175.5 that equals 369 though which would mean it would move down the ramp
alright and the other problem i had was simple it is a pulley question where 2 blocks are connected block one is on the incline and weighs 47kg and block 2 is on the other end of the pulley and weighs 35kg, theres 4 parts but the only one i need help with is a will the blocks move if m2 is...
