?A 1,800-kg pile driver is used to drive a steel I-beam into the ground. The pile driver falls 3.60 m before coming into contact with the top of the beam, and it drives the beam 14.2 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.

Now let’s apply the work–energy theorem to a more complex, multistep problem. In a pile driver, a steel hammerhead with mass 200 kg is lifted 3.00 m above the top of a vertical I-beam that is to be driven into the ground (Figure 1) . The hammer is then dropped, driving the I-beam 7.40 cm farther into the ground. The vertical rails that guide the hammerhead exert a constant 60.0 N friction force on it. Use the work–energy theorem to...

A pile driver lifts a 300 kgkg weight and then lets it fall onto the end of a steel pipe that needs to be driven into the ground. A fall of 1.5 mm before striking the pipe drives the pipe in 35 cm. What is the average force that the weight exerts on the pipe? (Hint: Let the weight be the system) Express your answer with the appropriate units. ------------------------------------------------------------------- Can you explain why the average force is the force...

WORK AND ENERGY
The recently patented "Francis pile-driver" pounds piles into the ground by launching 15-kg bowling balls from a spring loaded gun, up around a frictionless loop-de-loop of radius r = 8 m, and down onto the pile. When the spring is compressed by delta s = 2 m the bowling balls have a speed of 20 m/s at the top of the loop, as shown. (You may assume g = 10m/s^2.) Find the work done by the frictionless...
