True

False

Question 9

9.

9. Mike's car, which weighs 1,000 kg, is out of gas. Mike is trying to push the car to a gas station, and he makes the car go 0.05 m/s/s. Someone stated that hi is applying a force of 500 N. This statement is:

True

False

Is traveling at constant velocity

Has a constant acceleration

Is not experiencing a change in position

There isnt enough information
