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

A

`vecv = -2hatj`

B

`vecv = -1.5 hatj m/s`

C

`vecr = (4.5 hati-2.25 hatj)m`
