Conservation of Energy

In physics, the rule of the conservation of energy states that energy doesn’t disappear from the atmosphere; instead, it changes its form from one type to another. Energy is one of the most important physical quantities in nature, and it cannot be created or destroyed — only transformed.

In the selection of the ram of a pile driver, it is desired that the ram lose all of its kinetic energy at each blow. Hence, the velocity of the ram is zero immediately after impact. The mass of each pile to be driven is 340 kg, and experience has shown that a coefficient of restitution of O.25 can be expected. What should be the mass m of the ram? Compute the velocity v of the pile immediately after impact if the ram is dropped from a height of 3.3m onto the pile.

In the selection of the ram of a pile driver, it is desired that the ram lose all of its kinetic energy at each blow. Hence, the velocity of the ram is zero immediately after impact. The mass of each pile to be driven is 300 kg, and experience has shown that a coefficient of restitution of 0.36 can be expected. What should be the mass m of the ram? Compute the velocity v of the pile immediately after impact if the ram is dropped from a height of 2.6 m onto the pile. Also compute the energy loss ΔE due to impact at each blow.
