InterviewSolution

1.	A stone falls from a ballon that id descending at a uniform rate of 12m/s. The displacement of the stone from the point of release after 10 sec isA. 490mB. 510mC. 610mD. 725m
Answer» Correct Answer - C Initial velocity of stone u=12m/sec downwards `therefore` displacement `h=ut+(1)/(2)"gt"^(2)` `=12xx10+(1)/(2)xx9.8xx(10)^(2)` `=120+400=610 m`
