#### Answer:

#### Explanation:

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).

where

m = mass (kg)

g = 9.8 N/kg

h = height (m)

#### Answer:

See the answer below...

#### Explanation:

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...
