How do you find the scalar product of two vectors, A=8m along the y-axis in the negative direction and B=15m, 30 degrees from the y-axis in the first quadrant. Thanks!

Answer 1

scalar product = dot product of two vector.

dot product is product of two vectors times the cosine of the angle between them. The angle between these two vectors is 150degrees

ScalarProduct=8*15*cos150
