If a 500-lb piler driver is raised to a height of 12 feet then dropped how much work was done on the pile driver in raising it?

60,000

hi eeeeee

6,000

To determine how much work was done on the pile driver in raising it, we can use the formula for work:

Work = Force × Distance × cos(θ)

In this case, the force is the weight of the pile driver, which is 500 lbs. The distance is the height it was raised, which is 12 feet. The angle θ between the force and distance is 0 degrees, since the force is acting vertically upwards.

Plugging these values into the formula, we get:

Work = 500 lbs × 12 feet × cos(0°)

cos(0°) is equal to 1, so the equation simplifies to:

Work = 500 lbs × 12 feet × 1

Calculating this equation, we find that:

Work = 6,000 foot-pounds

Therefore, the work done on the pile driver in raising it to a height of 12 feet is 6,000 foot-pounds.
