A 7.00 kg bowling ball is held 2.00 m above the ground. Using [tex]$g = 9.80 \, \text{m/s}^2$[/tex], how much energy does it have due to its position?

A. 68.6 J
B. 137 J
C. 274 J
D. 960 J

Answer :

To determine the energy due to the bowling ball's position, we use the gravitational potential energy formula:

[tex]$$
E_{\text{pot}} = mgh,
$$[/tex]

where
[tex]\( m = 7.00 \, \text{kg} \)[/tex] is the mass of the ball,
[tex]\( g = 9.80 \, \text{m/s}^2 \)[/tex] is the acceleration due to gravity, and
[tex]\( h = 2.00 \, \text{m} \)[/tex] is the height above the ground.

Substitute the given values into the formula:

[tex]$$
E_{\text{pot}} = 7.00 \times 9.80 \times 2.00.
$$[/tex]

Calculating the product:

[tex]$$
E_{\text{pot}} = 137.2 \, \text{J}.
$$[/tex]

Rounding this result to the nearest whole number gives:

[tex]$$
E_{\text{pot}} \approx 137 \, \text{J}.
$$[/tex]

Thus, the energy due to its position is [tex]\(\boxed{137 \, \text{J}}\)[/tex].
