Answer:
Distance, d = 0.049 meters
Explanation:
It is given that,
Mass of the pile, m = 2500 kg
It is dropped through a height of 8.0 m on each stroke, h = 8 m
The resisting force of the ground,
The work done in each stroke is equal to the potential energy of the pile driver such that,
Work done due to resistive force is :
So,
d is the distance covered by the post driven in on each stroke.
d = 0.049 meters
So, on each stroke the post driven is 0.049 meters far. Hence, this is the required solution.
