A) \[1\text{ }m/{{s}^{2}}\]
B) \[2\text{ }m/{{s}^{2}}\]
C) \[10\text{ }m/{{s}^{2}}\]
D) \[20\text{ }m/{{s}^{2}}\]
Correct Answer: A
Solution :
\[{{v}^{2}}-\text{ }{{\text{u}}^{\text{2}}}\text{= 2aS}\] \[\Rightarrow a=\frac{{{\text{u}}^{\text{2}}}\text{ }}{\text{2aS}}=\frac{{{\left( 20 \right)}^{2}}}{2\times 200}=1m/{{s}^{2}}\]You need to login to perform this action.
