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
10. The amount of inertia an object has depends on the object's:
Acceleration
Velocity
Mass
Force
11. If an object is not at rest, and no external force is acting on it, then we can assume the object:
Is traveling at constant velocity
Has a constant acceleration
Is not experiencing a change in position
There isnt enough information
