The gravitational potential energy (PE) of an object with respect to ground level is given by the formula:
PE = mgh
where m is the mass of the object in kilograms, g is the acceleration due to gravity (9.81 m/s^2 on Earth), and h is the height of the object above ground level in meters.
Using this formula, we can calculate the gravitational potential energy of a 10.0 kg lead fishing weight when it is 2.00 m above the surface of the ground:
PE = (10.0 kg)(9.81 m/s^2)(2.00 m)
PE = 196.2 joules
Therefore, the 10.0 kg lead fishing weight has 196.2 joules of gravitational potential energy with respect to ground level when it is 2.00 m above the surface of the ground.
