#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#

None of the above. Velocity is a vector .

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