A) \[~-2.0\text{ }m/s\]
B) \[-1.0\text{ }m/s\]
C) \[-1.5\text{ }m/s\]
D) \[~1.0\text{ }m/s\]
Correct Answer: C
Solution :
The \[x-\]component of velocity \[{{v}_{x}}={{v}_{ax}}+{{a}_{x}}t=3-t\,m/s.\] The y- component is \[{{v}_{y}}={{v}_{ay}}+{{a}_{y}}t=-0.5t\frac{m}{s},\]when the particle reaches its maximum\[x-\]coordinate, \[{{v}_{x}}=0,\]or \[t=3\sec .\] The\[y-\]component of the velocity at this time is \[{{v}_{y}}=-0.5\times 3=-1.5\,m/s\] Hence, the correction option is [c].You need to login to perform this action.
