#|vecV| ~~ 9.76 " units"#

#hatV = -0.87hati + 0.49hatj#

Explanation:

According to the question,

#vecV = -8.5hati+4.8hatj#

#|vecV| = sqrt((V_h)^2 + (V_v)^2)#

#|vecV| = sqrt((-8.5)^2 + (4.8)^2)#

#rArr|vecV| ~~ 9.76 " units"#

#hatV = vecV/|vecV|#

#hatV = (-8.5hati+4.8hatj)/9.76#

#hatV = -0.87hati + 0.49hatj#
