A body of mass $\displaystyle 10$ kg is moving with an initial speed of $\displaystyle 20$ m/s. The body stops after $\displaystyle 5$ s due to friction between body and the floor. The value of the coefficient of friction is: (Take acceleration due to gravity $\displaystyle \mathrm{g}=10 \mathrm{~ms}^{-2}$ )
Official answer
From NTA’s final answer key for this paper.
