A) 0.02
B) 0.03
C) 0.06
D) 0.01
Correct Answer: C
Solution :
[c] \[{{f}_{r}}=Ma\] \[\mu R=Ma\] \[\mu \,Mg=Ma\therefore R=Mg\] \[\mu =\frac{a}{g}...(1)\] \[\mu =\frac{6}{10\times 10}=0.06\] \[v-u=at\] \[o-u=at[v=o]\] \[a=\frac{u}{t}=\frac{6}{10}=0.6m/{{s}^{2}}\] \[put\,value\,in\,(1)\] \[\mu =\frac{a}{g}=\frac{0.6}{10}=0.06\] \[v-u=at\] \[a=\frac{u}{t}=\frac{6}{10}m/s\] \[v=0\]You need to login to perform this action.
