Determine the magnitude and direction of the effective value of g at a latitude of 33.0° on the Earth. Assume the Earth is a rotating sphere.
ShawnD said:That is one hell of a question!
If you draw what it's asking, and line the equator up as your x axis, you will see that gravity is pulling at a 33 degree angle, but centrifugal force is pushing along the x axis.
For g, use that gravity
No. Centripetal means towards the center. Centrifugal means away from the center. The spinning motion of Earth tries to throw people off; away from the center.Chi Meson said:I'm sure ShawnD meant "centripetal force."
physicsss said:What is the velocity? And how do I find the angle? the hint says "from a line directly toward the center of the earth" I need some more help

Magnitude refers to the size or amount of a physical quantity, while direction refers to the orientation or path of that quantity.
To determine the magnitude of a vector, you can use the Pythagorean theorem to find the length of the vector. To determine the direction, you can use trigonometric functions such as sine and cosine to find the angle between the vector and a reference axis.
Magnitude alone refers to the size or amount of a physical quantity, while magnitude and direction together describe both the size and orientation of the quantity.
Determining the magnitude and direction of a vector is important because it allows us to accurately describe and analyze physical quantities, such as velocity or force, in a specific direction.
Yes, the magnitude and direction of a vector can change. This can occur due to external forces acting on the vector or changes in the reference frame used to measure the vector.
