Vector a→ has a magnitude of 8 units and makes an angle of 45° with the positive x-axis. vector b→ also has a magnitude of 8 units and is directed along the negative x-axis. using graphical methods, find (a) the vector sum a→ + b→ and (b) the vector difference a→ - b→

Hello there

the answer is

A + B = 6,123 units at angle 112,5 degrees.

A - B = 14,782 units at angle 22,5 degrees.

thank you

this is poiselle's equation from fluid mechanic in physics. mech eng

the motion of a pendulum is a classic example of mechanical energy conservation. a pendulum consists of a mass (known as a bob ) attached by a string to a pivot point. as the pendulum moves it sweeps out a circular arc, moving back and forth in a periodic fashion.
