Answer» Two vectors: for angular velocity and RADIUS VECTOR.To find: The velocity vector?Solution:Now we have given the vectors which are as follows: angular velocity (ω) = i - 2j + 3k radius vector (r) = i + 2j + kNow we know the relation between linear velocity and angular velocity which is: (ω) X (r) = vSo putting the values in formula, we get: v = ( i - 2j + 3k ) x ( i + 2j + k ) v = v = i(-2-6) - J(1-3) + k(2+2) v = i(-8) - j(-2) + k(4) v = -8I + 2j + 4kAnswer: So the velocity vector is -8i + 2j + 4k |
