Question #9dea4

Answer 1

`vec v=v_0+vec a*t`

`vec v=2 hat i+5 hat j +5 hat j*2`

`vec v=2 hat i+ 5 hat j+10 hat j`

`vec v=2 hat i+15 hat j`

`"the magnitude of v is "`

`v=sqrt(2^2+15^2)`

`v=sqrt(4+225)`

`v=sqrt 229`

`v=15.13 m/s`

Answer 2

None of the above. Velocity is a vector .

`mathbfv(2) = langle 2, 5 rangle + 2 langle 0, 5 rangle = langle 2, 15 rangle`
