A rigid body is rotating with angular velocity 2 rad/s about an axis in the

direction of the vector (i + j + k) and passing through the point Q = (0, 1, -1) on

the body. Find the linear velocity of the point P = (1, 0, 1) on the body.

(You may use the result v = ω x r .)

2. Relevant equations

v= ω x r

3. The attempt at a solution

Magnitude of vector joining P and Q = |P-Q| = r

.:. r = √6

v= ω x r

v= 2 x √6

v = 4.8990m/s

I'm assuming I'm completely wrong because the amount of work isn't enough for the amount of marks. I've seen similar questions online and I've noticed that x=1+t, y=1+2t and z=3t have been used in a number of the answers. Are these general rules or have they been derived from the question somehow? Any and all help would be greatly appreciated. Thanks.
