A) 1.5 unit, 4 unit
B) 3 unit, 4 unit
C) 16 unit, 1.6 unit
D) 16 unit, 3 unit
Correct Answer: A
Solution :
[a] \[v=\sqrt{3x+16}\] Squaring both sides \[\Rightarrow \,{{v}^{2}}=3x+16\] \[\Rightarrow \,{{v}^{2}}-16=3x\] Compare with \[{{v}^{2}}-{{u}^{2}}=2aS\] \[\begin{align} & \underset{{}}{\mathop{2a=3}}\,\underset{{}}{\mathop{{{u}^{2}}=16}}\, \\ & \,\,\,\,\,\Downarrow \,\,\,\,\Downarrow \\ & a=1.5m/su=4m/s \\ \end{align}\]You need to login to perform this action.
