Question

Please solve question no 13

Answer 1

This question can be solved mathematically which will take about 2-3 mins but can be solved using common sense in just 2 sec

If the object passes a height 5 in 10 sec then obviously the time of flight will be greater then 10(the object should stay in the air for a time greater than 10sec) compare it with some practical example if you dont get it

None of the option except 3 will give a value greater than 10 hence theres your answer
