A) 0.4
B) 0.2
C) 0.6
D) 0.8
Correct Answer: B
Solution :
At equilibrium \[{{\operatorname{Ma}}_{o}} = \mu Mg\] \[{{a}_{o}} = \mu g\] \[{{\operatorname{v}}^{2}}-{{\operatorname{u}}^{2}}=2\operatorname{aS}\] \[0-{{\left( 6 \right)}^{2}}=-2\mu \operatorname{g}\times 9\][- sign for retardation] \[\mu =0.2\]You need to login to perform this action.
