Question

A pile driver of mass 150kg falls from a height of 5m on a pile and it is brought to rest in 0.5sec.Ignoring the motion of the pile, find the average force exerted on the pile.(take g=10m/s)​

Answer 1

Answer:

ok mate

Explanation:

force= m×g×h =mass into gravity into height.

m= 150kg

g= 10m/s

h=. 5m

f= 150× 10× 5

=7500 Newton (N)

Answer 2

Answer:

I think

FORCE = MASS × GRAVITY × HEIGHT = 150000 g × 5 m × 0.5 s = 375000 N
