An object is moving in three dimensions, following a circular path at a constant radius from the origin, with a constant angular velocity ω--зі + k. if its linear velocity is expressed as v-vi + vyj+ vzk, what is the value of vy at the moment when its position vector is r-i+ 2j - 3k?

Explanation:

As we know that due to rotational motion the linear velocity of any point is given as

here we know that

now we have

So y component of velocity is given as

layers of the earth affect the waves and these effects are seen on instruiments such as seimometers

myth. it was once thought that animals, including cats and dogs, could only see in black and white. however, scientists have proven this to be a myth. in all animals, including humans, the perception of colour is determined by the presence of cells in the eye called cone photoreceptors.
