Answer:
Coefficient of sliding friction is 0.204
Explanation:
It is given that,
Initial velocity of the body, u = 6 m/s
Final velocity, v = 0 (as it comes to rest)
Distance, d = 9 m
We need to find the coefficient of sliding friction. Let it is equal to . Frictional force is given by :
Also,
...............(1)
Acceleration, a can be calculated using third equation of motion as :
The minus sign shows that the force is acting in opposite direction of frictional force.
Equation (1) becomes,
So, the coefficient of sliding friction is 0.204. Hence, this is the required solution.
