A) \[14m{{s}^{-1}},\text{ }-5m{{s}^{-2}}\]
B) \[19m{{s}^{-1}},-9m{{s}^{-2}}\]
C) \[-14m{{s}^{-1}},-5m{{s}^{-2}}\]
D) \[3m{{s}^{-1}},-5m{{s}^{-2}}\]
E) \[5m{{s}^{-1}},14m{{s}^{-2}}\]
Correct Answer: E
Solution :
\[v=\frac{dy}{dt}=0+5+14t\] At \[t=0,\text{ }{{v}_{0}}=5\text{ }m/s\] \[a=\frac{dv}{dt}=0+14=14m/{{s}^{2}}\]
