1. The problem statement, all variables and given/known data 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.
