Finding Magnitude and Direction of Vector Addition and Subtraction

AI Thread Summary
Vector A has a magnitude of 81 units directed due west, and vector B has the same magnitude directed due south. The resultant vector A + B can be calculated using the Pythagorean theorem, resulting in a magnitude of approximately 114.6 units directed at an angle of 225 degrees relative to due west. For A - B, the magnitude is also 81 units, directed at an angle of 315 degrees relative to due west. Understanding vector addition involves visualizing the vectors as arrows and applying geometric principles to find the resultant. The discussion emphasizes the importance of drawing the vectors for clarity in solving the problem.

vector A has a magnitude of 81 units and points due west, while vector B has the same magnitude and points due south. Find the magnitude and direction of (a) A + B and (b) A - B . Specify the directions relative to due west.

(a) Magnitude and direction of A + B = and o
(b) Magnitude and direction of A - B = and o
Hi folks any idea?

Try drawing it out firstly and what does A+B mean in vector notation? (How do you 'add' two vectors?)

Thread 'Collision of a bullet on a rod-string system: query'

In this question, I have a question. I am NOT trying to solve it, but it is just a conceptual question. Consider the point on the rod, which connects the string and the rod. My question: just before and after the collision, is ANGULAR momentum CONSERVED about this point? Lets call the point which connects the string and rod as P. Why am I asking this? : it is clear from the scenario that the point of concern, which connects the string and the rod, moves in a circular path due to the string...
