(1) What is the angle, 0, between two vectors, A and B, if | B| = B? (2) An object is moving clockwise in a circle of radius, r. Draw a vector, F, from the center of the circle to the object. What are the magnitude and the direction of Fx , where is the velocity vector of that object? What happens to your result if the object is instead moving counter clockwise? Quantities like this will be very mportant when we discuss torque and angula momentum in a couple of weeks
