Kinematics help -- object is dropped from a height h
An object is dropped from a height h and strikes the ground with a velocity v. If the object is dropped from a height of 2h, which of the following represents its velocity when it strikes the ground?
A) v
B) 1.4v
C) 2v
D)4v
Not sure.
I thought that velocity in this situation would be represented as 2v, but the answer in my book says the correct answer is B. I wasn't quite sure how to figure that out or what the relevant equation for figuring this problem out might be.
