Question

A body is projected with velocity v, from the point A as shown in Figure. At the same time, another body is projected
vertically upwards from B with velocity 02. The point Blies vertically below the highest point. For both the bodies to
collide,v2/v1 is​

Answer 1

Answer:

v2/v1 is equivalent to t2/t1

try finding the time taken by the bodies or their masses and compare them

and if they r in opposite direction, then ans will be 0 cause, in 1 case work will be -ve and in the other case work will be +ve and the sum of - & + is 0

hope it would satisfy your doubt

pls mark me brainliest
