Aball rolls from point a to point b. the total energy of the ball at point a isn’t the same as the sum of its potential energy and kinetic energy at point b. which statement best explains this situation?
the rolling ball doesn’t follow the law of conservation of energy.
some of the ball’s energy is transformed to thermal energy.
the rolling ball loses some of its energy because of gravity.
the ball absorbs some of its own potential energy.

Part a determine the magnitude of the x component of f using scalar notation. fx f x = nothing lb request answer part b determine the magnitude of the y component of f using scalar notation. fy f y = nothing lb request answer part c determine the magnitude of the z component of f using scalar notation. fz f z = nothing lb request answer provide feedback figure1 of 1a force vector acting on a ring attached to the ground is shown in the xyz space together with its x, y, and z components lying on the corresponding positive axes. the ring is located at the origin. force f is located in the first octant. f makes an angle of 60 degrees with its x component and an angle of 45 degrees with its y component. a force vector acting on a ring attached to the ground is shown in the xyz space together with its x, y, and z components lying on the corresponding positive axes. the ring is located at the origin. force f is located in the first octant. f makes an angle of 60 degrees with its x component and an angle of 45 degrees with its y component.
