Kinetic energy varies jointly with the mass (m) of an object and the square of it's velocity (u). A ball with a mass of 6 kg rolls with a velocity of 10 m/s and creates 300 joules of kinetic energy. How much kinetic energy would a ball with a mass of 3 kg and a velocity of 5 m/s create? (First find the constant of variation)

A. 75 joules
B. 37.5 joules
C. 202.5 joules
D. 7.5 joules

On traditional maps, earth is represented in a flat plane, or by euclidean geometry. however, a globe is a more accurate model that comes from elliptical geometry.how does a globe represent the fact that there are no parallel lines in elliptical geometry? the equator is not parallel to any other latitudinal lines. the north and south poles are never connected by a geodesic. the geodesics connecting the north and south poles never intersect. the geodesics connecting the north and south poles intersect at both of the poles.
