What should be the initial potential energy of a pile driver ram so that when it strikes piles, it delivers a kinetic energy of 20 KJ?

the initial potential energy should be 20 kJ.

Explanation:

Based on law of conservation of energy, the kinetic energy delivered by the pile driver when it strikes the piles, should be equal to the initial potential energy.

Since the final kinetic delivered is given as 20 kJ, then the initial potential energy should be 20 kJ.

Therefore, the initial potential energy should be 20 kJ.

the simple machine has three main features. they are:

fulcrum is the center point or pivot point of the machine. effort is input force/ applied force. load is external force/ output.

the keisha 's machine labels are

x : load

y: fulcrum

z: lever

yo yo yo its papaguy in the house lol

okay, ima .

um it shows links to uh so kinda microsoft website is that were ima go or no? ?
