Answer:
Ep=0.66J
Explanation:
We have to use the formula for potential energy
[tex]E_{p}=Mgh[/tex]
where g is the gravity constant, h is the heigth an M is the mass. By replacing and taking into account the appropriate units (kg and m) we have
100g=0.1kg
68cm=0.68m
[tex]E_{p}=(0.1kg)(9.8\frac{m}{s^{2}})(0.68m)=0.66J[/tex]
I hope this is useful for you
