A particle leaves the origin with an initial velocity `vecv=3hati` m/s and a constant acceleration `veca=(-hati-0.5hatj) m//s^(2)` in free space. Its velocity `vecv` and position vector `vecr` when it reaches its maximum x-coordinate are

`vecv=-2vecj`

`vecv=1.5vecj`

`vecr=(4.5veci-2.25vecj)`

`vecr=(3hati-2hatj)`
