a 40 kg dog is sitting on top of a hillside and has a potential energy of 1,568 j. what is the height of the hillside? (formula: $pe = mgh$)\n3.9 m\n4.0 m\n39.2 m\n40.0 m

Answer

Answer:

B. 4.0 m

Explanation:

Step1: Identify given values

$PE = 1568\ J$, $m = 40\ kg$, $g= 9.8\ m/s^{2}$ (approximate value of acceleration due to gravity on Earth)

Step2: Rearrange formula for height

From $PE=mgh$, we get $h=\frac{PE}{mg}$.

Step3: Substitute values

$h=\frac{1568}{40\times9.8}=\frac{1568}{392}=4.0\ m$
