Correct Answer: A
Solution :
The free body diagram showing the situation is as below. R is the reaction of the floor on the ladder, w the weight of ladder. \[v=0\]. Also \[\Rightarrow \] Given, \[\frac{{{h}_{1}}}{{{h}_{2}}}=\frac{u_{1}^{2}}{u_{2}^{2}}\] \[{{u}_{2}}=2{{u}_{1}},\,{{v}_{1}}=u\] \[\text{=}\frac{\text{Total}\,\text{distance}}{\text{Velocity}}\]You need to login to perform this action.
