A) \[3\sqrt{{}}3\]
B) 15
C) 18
D) 21
Correct Answer: C
Solution :
Along y-axis Initial velocity \[=v\,cos60{}^\circ \] \[=6\,cos60{}^\circ =\frac{6}{2}=3\] Acceleration\[(a)=3\text{ }m/{{s}^{2}}\] Time\[(t)=5s\] \[\therefore \]Final velocity\[=V\] \[V=u+at=(3+3\times 5)=18\text{ }m/s\].You need to login to perform this action.
