If u_(1), u_(2) and v_(1), v_(2) are the initial and final velocities of two particles before and after collision respectively, then (v_(2)-v_(1))/(u_(1)-u_(2)) is called ___________.

If u_(1), u_(2) and v_(1), v_(2) are the initial and final velocities of two particles before and after collision respectively, then (v_(2)-v_(1))/(u_(1)-u_(2)) is called ___________.

Two objects A and B are horizontal at angles 45^(@) and 60^(@) respectively with the horizontal. It is found that both the objects attain same maximum height . If u_(A) and u_(B) are initial speeds of projection of objects A and B respectively , then u_(A)//u_(B) is
