Point 1 h Point 2 Point 3 2016 Pearson Education, Inc. An I-beam is driven into the ground using a pile driver. The mechanism drops a massive steel hammer onto the beam from a height onto the beam. The 196 kg hammer is moving at 7.34 m/s at point 2 in the figure, and stops at point 3 after driving the beam d = 7.83 cm deeper into the ground. What is the magnitude of the force that the hammer exerts on the beam? (1 m = 100 cm) For a large force, it is convenient to use units of kiloNewtons. ( 1 kN = 1000 N) F = KN
