I want to see the solving steps

4.214 N

Explanation:

Since the ball reaches a constant terminal velocity, then the net force = 0 because the acceleration = 0

If we draw a free body diagram, we will find that all forces acting on the ball are:

If F(net) = 0, then gravitational force = air resistance = Mass * free-fall acceleration = 0.43*9.8 = 4.214 N

they are non-matter

explanation:

they are non-matter. basically, any type of energy or any abstract concept is an example of something that does not matter. other examples include dreams, magnetism, radio, and hate

answer would be letter choice (a),   a ball resting on a shelf. would be another example of potential energy   >   stored energy > not moving.

a ball spinning on a finger   >   kinetic energy > moving energy

a ball rolling on the ground   >   kinetic energy   > moving energy

a   ball flying through the air   > kinetic energy   >   moving energy

hope that                                         : )
