A 900 kg car accelerates 2 m/s2 to the right. What is the net force acting on the car?

1800 N to the left
450 N to the right
450 N to the left
1800 N to the right

F = m a and acceleration is in the same direction as the net force.

The net force on the car is 1800 N to the right.

b

explanation:

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                                         : )
