Show that A = î- 5 j are parallel to each other. B= 2î-10 j are parallel to each other.

We are given:

2 Vectors A and B

A = î -  5j

B = 2î - 10j

Proving that the given vectors are Parallel:

We can rewrite the Vector B as: B = 2(î - 5j)

Since A = î - 5j

Vector B can be written as:

B = 2(A vector)

this means that the magnitude of Vector B is twice of vector A but their direction is the same

Since the 2 vectors are moving in the same direction, they are parallel

0.11 m/s and 0.28 m/s should be correct
