A) 300 m
B) 400 m
C) 150 m
D) 75 m
Correct Answer: D
Solution :
Here: \[u=10\text{ }m/s,\text{ }v=20\text{ }m/s,\text{ }t=5\text{ }sec\] From equation of motion, \[\upsilon =u+at\] \[20=10+a\times 5\] So, \[a=2\,m/{{s}^{2}}\] Now from formula, \[{{\upsilon }^{2}}={{u}^{2}}+2as\] \[{{20}^{2}}={{10}^{2}}+2\times 2s\] so, \[s=\frac{300}{4}=75m\]You need to login to perform this action.
