Aball of mass 0.7 kg flies through the air at low speed, so that air resistance is negligible. (a) what is the net force acting on the ball while it is in motionwhich components of the ball's momentum will be changed by this force? what happens to the x component of the ball's momentum during its flight? what happens to the y component of the ball's momentum during its flight? it decreases. what happens to the z component of the ball's momentum during its flight?
