Vector A has a magnitude of 5.00 units, and vector B has a magnitude of 9.00 units. The two vectors make an angle of 50.0° with each other. Find A B .

To determine

The dot product of two vectors A and B.

Explanation of Solution

The magnitude of vector A is 5units, the magnitude of vector B is 9units and the angle between the two vectors is 50.0°.

Write the formula to calculate the dot product of two vectors

    AB=ABcosθ

Here, A is the magnitude of the vector A, B is the magnitude of the vector B and θ is the angle made by the two vectors with each other.

Conclusion:

Substitute 5.00 for A, 9
