A) 200m
B) 300m
C) 500 m
D) 250 m
Correct Answer: D
Solution :
\[u=0,v=180\,km/h=50\,m/s\] Time taken, t = 10 s \[a=\frac{v-u}{t}=\frac{50}{10}=5\,m{{s}^{-2}}\] Distance covered \[s=ut+\frac{1}{2}a{{t}^{2}}\] \[=0+\frac{1}{2}\times 5\times {{(10)}^{2}}\] \[=\frac{500}{2}\Rightarrow =250\,\,m\]You need to login to perform this action.
