A) \[75m\]
B) \[160m\]
C) \[100m\]
D) \[150m\]
Correct Answer: B
Solution :
Since stopping distance, \[s=\frac{{{v}^{2}}}{2a}\] For case \[1,40=\frac{{{(40\times \frac{5}{18})}^{2}}}{2a}..........(1)\] For case 2, \[s=\frac{{{(80\times \frac{5}{18})}^{2}}}{2a}...........(2)\] From (1) and (2), \[s=160m\]You need to login to perform this action.
