A) \[20\,m/{{s}^{2}}\]
B) \[10\,m/{{s}^{2}}\]
C) \[5\,m/{{s}^{2}}\]
D) \[2.5\,m/{{s}^{2}}\]
Correct Answer: A
Solution :
Average acceleration \[=\frac{change\text{ }in\text{ }veloclty}{Time\text{ }taken}\] \[=\frac{-30\,m/s-18\,m/s}{2.4}\] \[=20\,m/{{s}^{2}}\]You need to login to perform this action.
