Answer:

4.69 inches

Step-by-step explanation:

sin = opposite/hypotenuse

sin 23 = a/12

To solve for a, multiply both side by 12, so a is by itself.

12 · sin23 = a/12 · 12

12 · sin23 = a

use your calculator to find the sin of 23, which is approximately 0.390731128

Multiply by 12

0.390731128 * 12 = 4.688

Now, formula for potential energy is;

P = mgd

where;

m is mass

g is acceleration due to gravity

d is distance covered

Now, the only option that falls into the input that affects energy expended is the distance covered. This is true because the more the distance covered, the higher the energy expended.
