Choose the correct alternatives:
(a) for a general rotational motion, angular momentum L and angular velocity ω need not be parallel
(b) for a rotational motion about a fixed axis, angular momentum L and angular velocity ω are always parallel
(c) for a general translational motion, momentum p and velocity v is always parallel
(d) for a general translational motion, acceleration a and velocity v are always parallel
The correct answer is
(a) for a general rotational motion, angular momentum L and angular velocity ω need not be parallel
(c) for a general translational motion, momentum p and velocity v is always parallel
