A) 8 m
B) 16 m
C) 24 m
D) 32 m
Correct Answer: D
Solution :
\[a=\frac{{{V}^{2}}-{{u}^{2}}}{2s}\]constant \[S\propto {{V}^{2}}={{u}^{2}}\frac{{{S}_{2}}}{{{S}_{1}}}=\frac{V_{2}^{2}-u_{2}^{2}}{{{v}^{2}}-{{u}^{2}}}\] \[(or)\,\,\frac{{{S}_{2}}}{8}=\frac{{{0}^{2}}-{{60}^{2}}}{{{0}^{2}}-{{30}^{2}}}\Rightarrow {{S}_{2}}=\frac{60\times 60\times 8}{30\times 30}=32m\]You need to login to perform this action.
