Ok. I am curious: how would you describe this property geometrically?

I see, very simple. Aside, is my geometrical justification valid?

Homework Statement The volume of a parallelepiped defined by the vectors w, u, \text{ and }v, \text{ where } w=u \times v is computed using: V = w \cdot (u \times v) However, if the parallelepiped is defined by the vectors w-u, u, \text{ and }v, \text{ where } w=u \times v instead, the volume...

I see, very simple. Thank you! So for (iii), block A would be more likely to slip when block B is at x=d because at x=d block B would have greater acceleration (would it?)

Homework Statement I do not fully grasp the concept behind all of these sub questions (i)-(iv). Homework Equations v=wAcos(wt) (SMH)? Friction Force = Coefficient of Friction * Normal Force The Attempt at a Solution (i) Varying as simple harmonic motion sees varying acceleration as it...
