how much gravitational potential energy does the pile driver have when it is lifted to a height of 15m? show work please
energy=mass*g*height
and i don't get it
To calculate the gravitational potential energy of an object, you need to know its mass, the height it's lifted to, and the acceleration due to gravity. The formula for gravitational potential energy is:
Gravitational Potential Energy = mass × gravity × height
1. Determine the mass of the pile driver. Let's assume it is 1000 kg.
2. Determine the acceleration due to gravity. On Earth, it is approximately 9.8 m/s².
3. Determine the height the pile driver is lifted to. In this case, it is 15 m.
Now, plug these values into the formula:
Gravitational Potential Energy = 1000 kg × 9.8 m/s² × 15 m
Multiply the mass (1000 kg) by the acceleration due to gravity (9.8 m/s²) and the height (15 m):
Gravitational Potential Energy = 147,000 Joules
Therefore, the pile driver has a gravitational potential energy of 147,000 Joules when lifted to a height of 15m.
