Given:
• Mass of ball, m = 1.2 kg
,• Height, h = 2 m
Let's find the potential gravitational energy of the ball.
To find the potential gravitational energy (PE_G), apply the formula:
[tex]PE_G=m\times g\times h[/tex]Where:
m is the mass = 1.2 kg
h is the height = 2 m
g is acceleration due to gravity = 9.8 m/s²
Input values into the formula and solve:
[tex]\begin{gathered} PE_G=1.2\times9.8\times2 \\ \\ PE_G=23.52\text{ J} \end{gathered}[/tex]Therefore, the potential gravitational energy of the ball is 23.52 Joules.
ANSWER:
23.52 J
