Homework Statement You are given vectors A⃗ = 4.8 i^− 6.4 j^ and B⃗ = - 3.6 i^+ 6.8 j^. A third vector C⃗ lies in the xy-plane. Vector C⃗ is perpendicular to vector A⃗ and the scalar product of C⃗ with B⃗ is 19.0. Find the x -component of vector C⃗ . Find the y-component of vector C⃗ ...

Erm. I'd like someone to explain what I've done wrong, where I've gone wrong and what I need to do to make it un-wrong.

Homework Statement A centrifuge rotates at 12000rpm, what is the radians per second? If the radius of the centrifuge is 150mm, what is the centripetal acceleration? Homework Equations Angular Velocity: ω = Δθ/Δt (maybe, not sure) Centripetal Acceleration: a = v2 / r The Attempt at a...
