Question

1)ln Eq. (5.1), the velocities, Vi and vf denote, respectively, the initial velocity of m and the final velocity of M in elastic collision. These two velocities are taken to be negative, because MV,+ m(-v) - M(-V)+ m a)vi is in the opposite direction of vf b)The value of vi does not depend on that of vf c)Vi and vf represent velocities of objects moving from left to right, while all velocities to the left are considered positive d)vi and vf represent velocities of objects moving from right to left, while all velocities to the right are considered positive

Explanation / Answer

The correct option is d) Wherein Vi and Vf represent the velocities of objects moving from right to left, while all velocities to the right are considered positive.
