Explanation / Answer

a. Fred's ball is hollow. i.e it is lighter than Betty's ball and thus has less inertia. Similarly, barney's ball is less heavier than btty's ball as it is smaller bu heavier than fred's as it is not hollow. And wilma's ball have less mass than all other balls.

Be> Ba > F > W.

now, more inertia means more time to get moving. So now it becomes just a matter of comparing Inertia.

Ba < Be

F < Ba

Be > W

F < Be

W < Ba

F > W
