AN ABJECT IS DROPPED FROM REST AT A HEIGHT OF 150 M AND SIMULTANEOUSLY ANOTHER OBJECT IS DROPPED FROM REST AT A HEIGHT OF 100 M.WHAT IS THE DIFFERENCE IN THEIR HEIGHTS AFTER 2 SECONDS,IF BOTH THE OBJECTS DROP WITH SAME ACCELERATIONS? HOW DOES THE DIFFERENCE IN HEIGHTS VARY WITH TIME?

Expert Answer:
The two objects fall with same acceleration simultaneously. Hence, after 2 seconds the difference in their heights will still be 50 m.
Hence, the height of first object after 2 seconds is 130 m.
Similarly the height of second object is
Hence, the height of second object after 2 seconds is 80 m.
So, the difference is same, i.e. 50 m.
Hence, we can conclude that the difference in height of the two objects does not depend on time and will always be same.
