A) \[8m{{s}^{-2}}\]
B) \[4m{{s}^{-2}}\]
C) \[2m{{s}^{-2}}\]
D) \[1m{{s}^{-2}}\]
Correct Answer: A
Solution :
[a] \[\frac{{{v}_{1}}}{a}=\frac{\Delta {{t}_{1}}}{2}=1.5\] \[\frac{{{v}_{2}}}{a}=\frac{\Delta {{t}_{2}}}{2}=1\] \[d=\frac{v_{1}^{2}-v_{2}^{2}}{2a}\Rightarrow a=8\operatorname{m}/{{s}^{2}}\]You need to login to perform this action.
