On a planet where

g = 12\,\text{m/s}^2

, a

6.0\,\text{kg}

crate is moved relative to a reference level as follows: it is first lowered

1.5\,\text{m}

, then raised

0.80\,\text{m}

, and finally lowered an additional

0.30\,\text{m}

to its final position. Calculate the net change in the crate’s gravitational potential energy with respect to the reference level.
