(a) What is the sum of the following four vectors in unit-vector notation? For that sum, what are (b) the magnitude, (c) the angle in degrees, and (d) the angle in radians? Positive angles are counterclockwise from the positive direction of the x axis; negative angles are clockwise. ➡️ E: 6.00 m at +0.900 rad F: 5.00 m at -75.0° G: 4.00 m at + 1.20rad H: 6.00m at -210°

Given M = 6 î + 5 j – 6 k and N = 3 î - 3 j - 3 k, calculate the vector product M x N. j +

Two vectors have the following magnitude, A = 8.9 m and B = 7 m. Their vector product is:  A⨯B = -1.8 m i + 13.8 m k. What is the angle (in degrees) between the vectors A and B?

Answer must be in standard form scientific notation with SI units that do not have prefixes ( except for kg.) all angles and directions must be calculated to the nearest 0.1 deg. (Tenth of a degree) and entered in standard form scientific notation.

A vector a of magnitude 17 units and another vector b of magnitude 8.5 units differ in directions by 72°. Find (a) the scalar product of the two vectors and (b) the magnitude of the vector product a×b.

Given the pair of vectors, A = (9.00î − 5.00ĵ ) and B =(−3.00î + 9.00ĵ ),use the definition of a scalar product to determine the following.   (a) the scalar product (b) the angle between the vectors (Enter an answer between 0 and 180 degrees.)                      ° (c) the angle ? between the vector A and the +x axis (Enter an answer between 0 and 180 degrees.)                      ° (d) the angle ? between the vector B and the +y axis (Enter an answer between 0 and 180 degrees.)                      °
