A) 0
B) 0.5 m
C) 2m
D) none of these
Correct Answer: B
Solution :
\[\frac{V}{\left( \frac{1}{2} \right)}\,\,=\,\,2\,\,\,\,\,\,\,\,\,\,\,\therefore \,\,v=1\,\,m/s\] Area under the speed time curve from\[t\,\,=\,\,4s\text{ }to\text{ }t\,\,=\,\,5\,\,sec\]. \[r=\left[ \frac{1}{2}\left( \frac{1}{2} \right){{(1)}^{2}} \right]\,\,\times \,\,2\,\,=\,\,0.5\,\,m\]You need to login to perform this action.
