Answer:
Coefficient of friction will be 0.296
Explanation:
We have given initial speed of the stone u = 8 m /sec
It comes to rest so final speed v = 0 m /sec
Distance traveled before coming to rest s = 11 m
According to third equation of motion
So
Acceleration due to gravity
We know that acceleration is given by
So
So coefficient of friction will be 0.296
