The potential energy (PE) of an object is given by the formula PE = mgh, where m is the mass of the object, g is the acceleration due to gravity (approximately 9.8 m/s² on Earth), and h is the height above the ground.

In this case, we know that the potential energy of the object increases by 12 J (from 80 J to 92 J) when it is lifted by 2.8 m. We can set up the equation:

12 J = m * 9.8 m/s² * 2.8 m

Solving for m gives:

m = 12 J / (9.8 m/s² * 2.8 m) = 0.43 kg

So, the mass of the object is approximately 0.43 kg.
