A marble block of mass 2 kg lying on ice when given a velocity of 6 m/s is stopped by friction in 10 s. Then the coefficient of friction is (a) 0.02 (b) 0.03 (c) 0.04 (d) 0.06

Answer: (d). Retardation a = 6/10 = 0.6 m/s² a = μ g ⇒ μ = 0.6/10 μ = 0.06, so the answer is (d).

Friction Basics

A marble block of mass $2\text{ kg}$ lying on ice when given a velocity of $6\text{ m/s}$ is stopped by friction in $10\text{ s.}$ Then the coefficient of friction is

Show answer and solution

Answer: (d)

Retardation $a = \dfrac{6}{10} = 0.6\text{ m/s}^2$
$a = \mu g \Rightarrow \mu = \dfrac{0.6}{10}$
$\mu = 0.06$ , so the answer is (d).
