Question

Vector A with arrow has a magnitude of 5.35 units, and vector B with arrow has a magnitude of 9.09 units. The two vectors make an angle of 47.0° with each other. Find A with arrow · B with arrow.

Answer 1

33.167

Step-by-step explanation:

The dot product of two vectors is given by

A . B = A B Cos Ф

Where, A and B be the magnitudes of vector A and vector B.

So,

A . B = 5.35 x 9.09 x Cos 47

A . B = 33.167
