A) \[0.4\]
B) \[0.2\]
C) \[0.6\]
D) \[0.8\]
Correct Answer: B
Solution :
Given:\[u=6m/s,\,\,s=9m,\,\,v=0\] From equation of motion \[{{v}^{2}}={{u}^{2}}-2as\] \[0={{(6)}^{2}}-2\times a\times 9\] \[18a=36\] \[\Rightarrow \] \[a=2m/{{s}^{2}}\] Coefficient of sliding friction is given by \[\mu =\frac{a}{g}\] \[=\frac{2}{10}=0.2\]You need to login to perform this action.
