A drop hammer is released and falls 5m on to a forging. Find the downwards velocity of
the hammer when it strikes the forging.
If the forging is to be reduced by 5mm per strike, requiring a total energy consumption
of 15kJ per strike, calculate the required mass of the hammer.
Potential enegry at 5 m height is converted into kinetic energy before impactPotential energy stored in hammer at 5 m height is converted into K. E of hammer before impact
