Given the following vector, v, obtain the unit vector (u) that aligns with the direction of v.
v = 16 i - 12 j

Unit vector u in the direction of vector v, expressed as u = 4/5 i - 3/5 j.

Unit vector u in the direction of vector v, expressed as u = 3/20 i - 7/20 j.

Unit vector u in the direction of vector v, expressed as u = -3/5 i - 4/5 j.

Unit vector u in the direction of vector v, expressed as u = 16/5 i - 12/5 j.

Given the following vector, v, obtain the unit vector (u) that aligns with the direction of v.v = 16 i - 12 j
