A) \[25\,m\]
B) \[375\,m\]
C) \[360\,m\]
D) \[40\,m\]
Correct Answer: A
Solution :
The maximum distance covered by the vehicle before coming to rest \[=\frac{{{V}^{2}}}{2a}=\frac{{{(15)}^{2}}}{2(0.3)}=375m.\] The corresponding time \[t=\frac{V}{a}=\frac{15}{0.3}=50s\] Therefore after \[50s,\]the distance covered by the vehicle \[=375m\] from the instant of begining of braking. The distance of vehicle from the traffic after one minute \[=(400-375)\,m=25m\]You need to login to perform this action.
