Problema Solution
A 20 kg body is dropped from a height of 10 m and penetrates 0.50 m into a box of soil. What is the average retarding force that the soil exerts on the body?
what is the solution of this problem with answer 3900 Newton?
Answer provided by our tutors
The average retarding force that the soil exerts on the body is F
According to the energy conservation law:
mgh = Fs
F = mgh/s = 20 kg *9.8 kg/m^2 * 10 m/ 0.50 m = 3920 N
So the average retarding force that the soil exerts on the body is 3920 N
