Answer 1

hey

First we start with magnitude of B vector which is 25 units.

Now, to find the vector parallel to A vector let’s find the unit vector in the direction of A vector.

As we know, unit vector of A = vector A /(magnitude of Vector A)

unit vector A = (3i + 4j)/5

Now for the final answer just multiply magnitude of vector B with the unit vector in the direction of vector A.

The required answer would be 25*(3i+4j)/5 = 15i + 20j
