Draw a free-body diagram for each of the masses, set up coordinates *hint: it's much easier if you assign the x-axis as the direction of motion for each block, so that the coordinates shift, like the direction of motion*, and set up net force equations for each using Newton's second law. You...

So it does. I guess I was tired and was making mistakes in my calculations. Thanks! :)

Here is the question: Block A, with weight 3w, slides down an inclined plane S of slope angle 36.9 degrees at a constant speed while plank B, with weight w, rests on top of A and is attached by a cord to the wall. If the coefficient of kinetic friction is the same between A and B and between S...

Formation of Hydrazine from Ammonia and Chloramine in basic solution. NH3 + NH2Cl -> N2H4 + Cl- What are the coefficients of NH3, OH-, and N2H4 in the balanced equation? I basically just balanced the hydrogens with an H+, then those with OH-, and got: NH3 + NH2Cl + OH- ->N2H4 + Cl- + H2O...

The statement of relative accelerations is a_(block/table) = a_(block/wedge) + a_(wedge/table). Was I supposed to derive this from a similar statement of relative velocity? I don't know what it wants me to do.

I searched for this problem and could not find satisfactory information or information that applied to my specific concerns. The wedge of mass M is resting on a horizontal surface. A block of mass m is placed on the wedge and the whole system is released from rest. There is no friction...
