Answer:
669042 N upward
Step-by-step explanation:
= Work done by gravity on pile driver
= Work done by beam
u = Initial velocity
v = Final velocity
m = Mass of pile driver = 2200 kg
g = Acceleration due to gravity = 9.81 m/s²
h = Height the pile driver falls = 4.2 m
d = Bend in beam = 14 cm
Total work done = Change in Kinetic energy

The force the beam exerts on the pile driver while the pile driver is brought to rest is 669042 N upward
