Hi, I am in physic I and they give me the problem  The earth's radius is 6.37×106m; it rotates once every 24 hours. The angular speed is ω = 7.3×10−5 rad/s   The speed of the point on the equator is v = 460 ms They want to know what is the speed of a point on the earth's surface located at 2/5 of the length of the arc between the equator and the pole, measured from equator? (Hint: what is the radius of the circle in which the point moves?)   Please explain in detail how to get this because I asked before and the answer is wrong. I have one more try. Please help! Thank you!

Torque

Torque is the rotational equivalent of linear force in physics and mechanics. Based on the course of study, it is also known as the moment of force, rotational force, or turning effect.
