To find the height to which the backpack is lifted, we can make use of the formula for gravitational potential energy:

Potential Energy = mass × gravity × height

Given:
Mass (m) = 8 kg
Gravitational Potential Energy (PE) = 54.9 J
Acceleration due to Gravity (g) = 98 m/s^2

We need to rearrange the formula to solve for height:

height = PE / (m × g)

Substituting the given values, we have:

height = 54.9 J / (8 kg × 98 m/s^2)

Now, let's calculate the height:

height = 0.0699 m

Therefore, the backpack is lifted to a height of approximately 0.0699 meters.
