Vector A has a magnitude of 2.2 units, vector B has a magnitude of 10 units, and Vector A times Upper B has a value of 14.0. What is the angle between the directions of Vector A and Vector B?

Answer 1

not sure what Upper B means

Answer 2

It should be Vector B instead of Upper B

Answer 3

when you say A times B, is that the dot product, or the cross product?

Answer 4

The dot product

Answer 5

|A| |B| cos theta = A dot B

2.2 * 10 * cos theta = 14

theta = cos^-1 (14/22)

theta = 50.5 degrees
