Answer 1

Answer:

A body is falling freely from a point A at a certain height from the ground and passes through points B,C and D (vertically as shown) so that BC=CD. The time taken by the particle to move from B to C is 2 seconds and from C to D 1 second. Time taken to move from A to B in seconds is

Answer 2
