Homework Statement
I)The mass of the moon is 7.35*10^22 kg. In inertial coordinates, the moon orbits the Earth in 27.3 days at an average distance of 3.84*10^5 kg. Calculate the centripetal force on the moon.
II)The mass of the moon is .0123 times that of earth. Since the Earth is...
Looking at a graph of AxB, I think I can see why that (AxB)xB would give me a vector perpendicular to B in the plane, and I'd just have to apply the dot product to get the component of A in the direction of B.
Homework Statement
vector A = 1.5i + 6.7j - 7.4k
vector B= -8.2i + 6.5j + 2.3k
(f) What is the magnitude of the component of vector A perpendicular to the direction of vector B but in the plane of vector A and B.
