Answer:
Part 1)
Projection of vector A on vector B equals 19 units
Part 2)
Projection of vector B' on vector A' equals 35 units
Step-by-step explanation:
For 2 vectors A and B the projection of A on B is given by the vector dot product of vector A and B
Given
Similarly vector B is written as
Thus the vector dot product of the 2 vectors is obtained as
Part 2)
Given vector A' as
Similarly vector B' is written as
Thus the vector dot product of the 2 vectors is obtained as
