- a car = 25m/s
- a person running = 6m/s
- a person walking = 3m/s

3. Which of these steps is the first in an answer to why an object reaches terminal velocity?
- acceleration decreases until the resultant force is 0
- the object accelerates
- the force of gravity is more than the force of air resistance
- as speed increases, air resistance increases
4. What is inertia?
- The tendency of an object to accelerate while falling
- The tendency of an object to change its momentum
- The tendency of an object to continue in its current state
- The tendency of an object to alter its current state
5. Which of these is not true of the law of conservation of momentum?
- If a stationary object hits a moving object, the total momentum before the collision is equal to the momentum of the stationary object after
- Works in a closed system
- Momentum before = Momentum After
- If a stationary object hits a moving object, the total momentum after the collision is equal to the initial momentum of the moving object
