At the "initial" location, the object's energy is all "potential". The rate of fall is not a part of the question - only the distance from the start (-2m).
m = mass (kg)
g = 9.8 N/kg
h = height (m)
See the answer below...
Suppose,it is at the initial height
Hence at the toppest point it has potential energy of
As any point of a body moving in a vertical way has a constant mechanical energy so we can write that:-
Here something wrong...
Need the question to be double checked...as
Though height might be negative but in this case...
