A) 60 \[m\]
B) 55 \[m\]
C) 25 \[m\]
D) 30 \[m\]
Correct Answer: B
Solution :
Distance = Area under v ? t graph\[={{A}_{1}}+{{A}_{2}}+{{A}_{3}}+{{A}_{4}}\] \[=\frac{1}{2}\times 1\times 20+(20\times 1)+\frac{1}{2}(20+10)\times 1+(10\times 1)\] \[=10+20+15+10=55\ m\]You need to login to perform this action.
