Nancy walks to school every morning. Her school is 2 miles away. Half-way to school she remembered that she left her backpack at home. She walks back to get her backpack and then speeds walks all the way to school. What was her distance traveled?
What is... 4 miles?

My brother likes to run really fast. He can run 30 feet every 2 seconds. If he ran for 30 seconds, how far would he get? (distance = speed x time).
What is 450 feet?

Given the equation for average acceleration: (Vf - Vi) ÷ time........ What is the acceleration of a person sliding down a hill if their speed at the end of the hill was 20 m/s, but the person got a push to start off at 3 m/s, and it took them 10 seconds to completely slide down the hill?
What is 1.7 m/s/s (down the hill)?........... (still give points if direction was left out)

Jim wants to race at thunder road. His dad tells him to make his car as light as possible so he has a better chance of winning. Which of Newton's laws would prove Dad to be correct? Briefly explain your reasoning.
Newton's second law: less mass = faster acceleration.

Paul lives in New York City where the blocks are perfectly square. Paul leaves his house and walks 2 blocks East, then 3 blocks North, 3 blocks West, then 3 blocks South. What is Paul's displacement?
What is 1 block West? (must include the direction)

On a Distance vs. Time graph, if the slope of the line looks like this: / What does that tell you about the speed of the object?
What is.... it is going a constant speed (same speed).

Michelle, weighs 400 N and wants to make a tire swing using a piece of rope that has a breaking point of 225 N, and a tire that weighs 80 N She ties one end of the rope to the tire and trows the other end over a tree branch and attaches it to the other side of the tire. Will the tire swing work?
No... (the tension in the rope will 240N which is more than the rope can handle. It will snap).

What net force is required to accelerate a car at a rate of 2 m/s/s if the car has a mass of 3,000 kg. Need correct units.
What is..... a force of 6,000 N.

A red car and a blue car are both moving East (blue car in front), except the blue car is moving more slowly. They both weigh the same amount. Once the red car hits the blue car, what happens to the red car's momentum? What happens to the blue car's momentum?
What is... the red car's momentum will lower the same amount the blue car's momentum increases.
