Answer:
411.6 Joules.
Step-by-step explanation:
The potential energy (PE) of an object at a certain height is given by the formula:
PE = m * g * h
where:
m = mass of the object (in kg)
g = acceleration due to gravity (approximately 9.8 m/s^2 on Earth)
h = height of the object above a reference level (in meters)
In this case, the mass of the object is 7 kg, the height is 6 m, and the acceleration due to gravity is 9.8 m/s^2. Therefore, we can calculate the potential energy as follows:
PE = 7 kg * 9.8 m/s^2 * 6 m
PE = 411.6 Joules
Therefore, the potential energy of the object is 411.6 Joules.
