7. Martina travels from her house to her mom's office building. From there, she walks to school. After school, she walks to the library and then to a friend's house before finally ending back at home. Find Martina's total distance traveled.

8. What is the acceleration of an object with mass of 42.6 kg when an unbalanced force of 112 N is applied to it?

9. If Shane and Susan both push on a box with a force of 25N, but in opposite directions, what will happen to the box?

10. Cara and Sam had to illustrate one of Newton's laws. They drew this model to represent the __________ law of motion which can also be represented by the equation F = ma.

11. The variables _______ and ________ affect the gravitational force between objects.

12. Which object would have a LARGER gravitational force acting upon it? (assume the objects are at the same height above the Earth.)

14. The Sun has more gravity than the planets in our solar system because the Sun is

15. The image shows that as the distance between two objects increases, the force of gravity ___________.

16. A car is stopped at a red light. When the light turns green, the car accelerates to a velocity of 150 m/s. The car takes 10 seconds to reach this velocity. Calculate the acceleration of the car.

17. A cup of coffee sits on the dashboard of an automobile. The car goes around a sharp curve. Even though you hold the cup still, coffee still splashes out. This can best be explained due to

18. You leave school and walk home, which is 1.5 miles East of the school. When you arrive home, you drop off your backpack and then proceed to walk over to your best friend's house, which is 0.5 miles back West. Find the total distance that you walked and the total displacement.

19. A 9 kg box is sitting on the edge of a table when suddenly it falls to the ground and hits your foot. You can calculate the weight of the box by using the formula, weight = mass x gravity. What is the weight of the box? *Remember gravity = 9.8 m/s2

20. Gravity on Earth is 9.8 m/s2. If an object has a mass of 5 kg, calculate its weight.

21. Isaac accelerated down the hill on his bike at a rate of 8 m/s2. If Isaac started from rest at the top of the hill and by the time he reached the bottom of the hill, his final velocity was 40 m/s, then how long did it take him to travel down the hill?

22. A car travels 675 miles West on the highway in 10 hours. Find the velocity of the car.

23. You hear a knock at the door so you open it and your dog runs outside. He runs east to your neighbor's house, which is 40 meters away. He then runs back 40 meters west and bolts through the door. This took him a total of 15 seconds. Find the speed and velocity your dog traveled.

24. A train travels from rest to a velocity of 80 m/s in just 20 seconds. Calculate the rate of acceleration for the train.
