A mass point at r = 3i + 4j - 2k rotates with angular velocity w = 2i - 3j + 5k around an axis. Calculate the linear velocity of the mass point given that the units for its coordinates are in metres and the units for the components of the rotational velocity are rad/s.

So, we have a poplar coordinate axis, on this axis the intial side is on the positive x-asis which then rotates at an angular velocity. let the distance travled at the arc by the mass point equal 2i-3j+5k and let the radius represent 3i+4j-2k, the linear velocity is the vector directed with a specific magnitude to the center. we then add the two values to get. (5i+j+3k)/2 phi.
