A) \[4\,\,m\]
B) \[200\,\,m\]
C) \[20\,\,m\]
D) none of these
Correct Answer: B
Solution :
If the acceleration is\[f\], then \[f=\frac{40-0}{10}m/{{s}^{2}}\] \[(\because \,\,v=u+ft)\] and displacement in\[10\,\,s\] \[=\left( 0\times 10+\frac{1}{2}\times 4\times {{10}^{2}} \right)m\] \[\left( \because \,\,s=ut+\frac{1}{2}f{{t}^{2}} \right)\] \[=200\,\,m\]You need to login to perform this action.
