1.	A body is thrown vertically upwards at t = 0. It is at a height 80 m at instants t_(1) and t_(2). Also, it is at a height 60 m at instant t_(1) and t_(2). Then:
Answer» `t_(1) + t_(2) = t'_(1) + t'_(2)` `t_(1) + t_(2) GT t'_(1) + t'_(2)` `t_(1) + t_(2) lt t'_(1) + t'_(2)` NONE of these Solution :`t_(1) + t_(2) = t'_(1) + t'_(2)` Sum of TIME remain same.
