A block moving on a surface with a velocity of comes to rest because of surface friction over a distance of . The coefficient of dynamic friction is (take, )
Step 1: Defining the coefficient of friction
Step 2: Given data
The initial velocity of a body,
The final velocity of a body,
The distance covered by a body,
Step 3: Calculating the coefficient of dynamic friction
Using the third equation of motion, we get
Hence, option(A) is correct answer.
