I need so much help, thanks in advance!

Determine the gravitational energy of your 3kg physics binder
a) relative to the table it sits on
b) relative to the floor, 0.68 meters below the book
c) relative to the floor 2.5 meters above the book

a. zero

b. mgh=3kg*9.8N/kg*.68m
c. mgh=3kg*9.8N/kg*-2.5m

Sure! I'd be happy to help you.

To determine the gravitational energy of an object, we use the formula: gravitational energy = mass x gravitational acceleration x height.

Before we proceed, we need to know the value of the gravitational acceleration. On Earth, the standard value is approximately 9.8 meters per second squared (m/s²). We'll use this value for our calculations.

a) To determine the gravitational energy of the 3kg physics binder relative to the table it sits on, we need to know the height of the binder above the table. Assuming it is at rest on the table, the height is zero. Hence, the gravitational energy relative to the table is also zero.

b) To determine the gravitational energy of the binder relative to the floor, which is situated 0.68 meters below the book, we can use the formula. Given:
- Mass (m) = 3 kg
- Gravitational acceleration (g) = 9.8 m/s²
- Height (h) = 0.68 m
we can plug in these values into the formula: gravitational energy = mass x gravitational acceleration x height.
So, the gravitational energy is calculated as follows:
gravitational energy = 3 kg x 9.8 m/s² x 0.68 m = 19.0984 Joules (J)
Therefore, the gravitational energy of the binder relative to the floor is approximately 19.0984 Joules.

c) To determine the gravitational energy of the binder relative to the floor, which is situated 2.5 meters above the book, we can use the same formula. Given:
- Mass (m) = 3 kg
- Gravitational acceleration (g) = 9.8 m/s²
- Height (h) = 2.5 m
we can calculate the gravitational energy as follows:
gravitational energy = 3 kg x 9.8 m/s² x 2.5 m = 73.5 Joules (J)
So, the gravitational energy of the binder relative to the floor located 2.5 meters above the book is approximately 73.5 Joules.
