how much gravitational potential energy does the pile driver have when it is lifted to a height of 15m? show work please
To calculate the gravitational potential energy (GPE) of the pile driver when it is lifted to a height of 15m, you can use the formula:
GPE = m * g * h
Where:
GPE is the gravitational potential energy
m is the mass of the pile driver
g is the acceleration due to gravity (which is approximately 9.8 m/s^2)
h is the height
To find the GPE, you will need to know the mass of the pile driver. Let's assume the mass of the pile driver is 1000 kg.
GPE = 1000 kg * 9.8 m/s^2 * 15 m
Now, you can calculate the GPE:
GPE = 147,000 joules
Therefore, the pile driver has a gravitational potential energy of 147,000 joules when it is lifted to a height of 15m.
