some one can help me with this problem;
an object is droped from a height of h and hits ground with a velocity of 2h which of the following represents its velocity when it hits ground?
1)v
2)1.4v
3)2v
4)4v

Thinking critically has nothing to do with it if the problem does not make any sense. The object cannot have a velocity of 2h if you previously define h as a distance, not speed, value. You cannot find the velocity of an object on impact in terms of v if you don't define what v is, unless you mean specifically that "use v=sqrt of 2gh" means v is represented as (2gh)^1/2, in which case for an object dropped from height h with 0 initial velocity, it will hit the ground at (2gh)^1/2 and the answer would be "v". Perhaps if you could clarify..
