1. A rigid body is rotating with angular velocity 6 rad s−1 about an axis in the direction of the vector (3, −2, 1) and passing through the point A(3, −2, 5). Find the linear velocity of the point P(3, −2, 1) on the body.

2. A force of 4 units acts through the point P(4, −1, 2) in the direction of the vector (2, −1, 4). Find its moment about the point A(3, −1, 4).
