A) zero
B) 0.2 m
C) 0.4 m
D) 0.8 m
Correct Answer: B
Solution :
From first equation of morion \[v=u+at\] \[0=-\,4+a\times (0.1)\] \[\Rightarrow \] \[a=40\,m\text{/}{{s}^{2}}\] \[\therefore \] \[s=\frac{{{v}^{2}}}{2a}\] \[\Rightarrow \] \[s=\frac{{{(4)}^{2}}}{2\times 40}\] \[\Rightarrow \] \[s=\frac{16}{80}\] \[\Rightarrow \] \[s=0.2\,m\]You need to login to perform this action.
