A) \[2\text{ }m/{{s}^{2}}\]
B) \[1\text{ }m/{{s}^{2}}\]
C) \[4\text{ }m/{{s}^{2}}\]
D) \[20\text{ }m/{{s}^{2}}\]
Correct Answer: A
Solution :
Initial velocity \[u=0\] Final velocity \[\upsilon =72km/hr\] \[=72\times \frac{5}{18}=20m/s\] Acceleration \[=\frac{\upsilon -u}{t}=\frac{20-0}{10}=2m/{{s}^{2}}\]You need to login to perform this action.
