A pile driver lifts a 450 kg 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 m before striking the pipe drives the pipe in 45 cm. What is the average force that the weight exerts on the pipe? (Hint: Let the weight be the system)
Homework Answers
Work, W = Fd = mgh
F x 0.45 = 450 x 9.8 x 1.5
Force, F = 14700 N

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...

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...

(non calculus based physics) Question 1 An Olympic weight lifter lifts an 1800 N set of weights from the ground to a vertical distance of 2.20 m above his head. Assuming he moves the weights at constant speed, how much work does the weight lifter do? Question 2 A 4.5 kg trunk, initially at rest, takes 2.0 s to slide 2.8 m down a rough 25° slope. Calculate: the work performed by the force of gravity. the amount of mechanical...
