A) \[\frac{g\mu }{v}\]
B) \[\frac{g}{v}\]
C) \[\frac{v}{g}\]
D) \[\frac{v}{g\mu }\]
Correct Answer: D
Solution :
Given, \[\Rightarrow \] final velocity = 0 Using \[\Delta x=(65+65)-120\] \[\Rightarrow \] \[\Delta x=10\,m\] \[\frac{\lambda }{2}\] \[\lambda \] (f is the force of friction) Retardation, \[=\left( 10-\frac{\lambda }{2} \right)\] \[=(2n)\frac{\lambda }{2}\] \[n=0,\,\,1,\,\,2,...\]You need to login to perform this action.
