- A 2,300-kg pile driver is used to drive a steel I-beam into the ground. The pile driver falls 4.20 m before coming into contact with the top of the beam, and it drives the beam 13.2 cm farther into the ground as it comes to rest. Using energy considerations, calculate the average force the beam exerts on the pile driver while the pile driver is brought to rest. magnitude N directionarrow_forwardWork is equal to force times the distance. This means that to do the same amount of work, a greater distance requires less force. Consider a see-saw in balance.

This force must be exerted over a greater distance, so the work done should be the same. In reality, because of the frictional force between the crate and the ramp, the work required is greater than that needed to lift the crate directly onto the truck. The mover does 4365 J of work sliding the crate up the ramp. The force the mover exerts on the crate is 1302 N. How long is the ramp?arrow_forwardChoose the correct answer choice.arrow_forward
