5) Keegan pushes a 80 kg model car and a 40 kg model car, each with the same amount of force. Which statement demonstrates an understanding of the force and the effect on the
object.
O The force on both model cars was the same; therefore, each model car pushes back with the same
amount of force.
O The force on both model cars was the same; however, each model car pushes back with a different
amount of force.
The 80 kg model car pushes back with double the force of the 40 kg model car, because it has double
the mass.
The 40 kg model car pushes back with a greater force than the 80 kg model car, because the 40 kg
model car moved faster and further.
