Figure shows four vectors A⃗ , B⃗⃗ , C⃗ , and D⃗⃗ with magnitude A = 5, B = 7, C = 9 and D = 11. Find out the angle between the
vectors A⃗ × B⃗⃗ and C⃗ × 2 D⃗⃗

when two balls of the different masses are dropped from equal height, they reach the ground at the same time .this is because they experience the same acceleration.

the acceleration is independent of mass.

thus when they are dropped they will always maintain the same velocity and travel the same distance (neglect air resistance of course) at the same time.

the components of a vector are the parts of the vectors that are to each other.
