1. A Basketball player stands at center court. She runs 19 m to the right in 5 s, then she turns around and runs 24 m to the left in the next 5 s. a. What distance did she travel during the last 5 s?
b. What was the average speed for the entire 10 s?
c. What is the displacement during the last 5s?
d . What is the total displacement?
e. What was the average velocity for the entire trip?

F. The player then returns to the center of the court in some amount of time. What was her velocity for the entire trip? How can you know her velocity if you don’t know exactly how much time she was moving?
3. You see a car moving at a constant velocity. You see the car move 21m in the first 4 seconds.
What is the velocity of the car?
How long will it take the car to reach a sign that is 112 m away?
4. A rocket’s speed increases from 10 m/s to 280 m/s in 9 seconds.
Use the formula the acceleration to find the acceleration of this rocket.
What is the rocket’s velocity after 12 seconds if the acceleration stays the same?
5. A racecar accelerates from a speed of 106 m/s to a complete stop in 6.8 seconds. What is its average acceleration for the car?
6. A car starting from rest accelerates at a rate of 4.0 m/s/s for 7 seconds
What is its final velocity at the end of 10.0 seconds?
How far did it travel?
7. The motion diagram shows the motion of an object during the first 4 seconds of its motion.
Write a motion claim supported by evidence about the motion of the object. Include information about the type of motion and direction.
Is the velocity of the object positive or negative? Justify your choice.
Is the acceleration be positive or negative? Justify your choice.
8. The tables below give data about a car during 4 seconds of its motion.
Make an X vs. T graph with labeled axes for the data provided.
What direction is the car moving, + or -? How do you know?
Is the Car’s velocity positive or negative? How do you know?
Looking at your graph in part a, Does the car speed up, slow down, or move with constant speed? Explain how the shape of the graph indicates the motion of the car.
Calculate the average velocity of the car between 0 and 4 seconds.

9. A car driving at 45 m/s applies the brakes and slows with and acceleration of at a rate of -7.0 m/s/s for 5 seconds.
What is its final speed of the car after 5 second?
How far did it travel? (must show a graph or a formula) ]

Question 1 what is amperage? is the rate of doing work. is the rate of flow of protons in electric current. represents the amount of pressure behind electron flow. is the rate of flow of electrons in electric current. 2 points question 2 what is voltage? is the rate of doing power. represents the amount of pressure behind electron flow. is the rate of doing work. is the rate of flow of electrons in electric current. 2 points question 3 what is power? is the rate of flow of protons in electric current. is the rate of flow of electrons in electric current. is the rate of doing work. represents the amount of pressure behind electron flow. 2 points question 4 if we multiply volts times amps we get what? power circuit work current 2 points question 5 what are two ways alternating currents are similiar? in both ac and dc electrons flow in the same pattern. in both ac and dc, the flow of electrons changes directions back and forth. both ac and dc are only possible in certain materials with atoms that will allow electron flow. both ac and dc involve the flow of electrons. 4 points question 6 how does the flow of electrons flow in an alternating current? the flow of electrons is always slower in an alternating current than within a direct current. the flow of electrons is not constant and forward; it changes direction back and forth. electrons flow from from a higher affinity to that of a lower affinity. electron flow is constant and only in a forward direction. 2 points question 7 what is the flow like in a direct current? the flow of electrons is not constant and forward; it changes direction back and forth. the flow of electrons is constant and only in a forward direction. the flow of electrons go from a higher affinity to a lower affinity. the flow of electrons are always faster in a direct current. 2 points question 8 how is an electric current able to flow? electrons flow from the higher affinity to lower affinity and electrical current is generated. protons flow from the higher affinity to lower affinity and electrical current is generated. the movement of protons from one atom to another leads to an electric charge. the movement of electrons from one atom to another atom in a line results in a flow of electric current. 2 points question 9 how do electrons move from the two different types of metal in a battery? protons flow from the metal with the lower affinity to the metal with higher affinity and electrical current is generated. electrons flow from the metal with the lower affinity to the metal with higher affinity and electrical current is generated. electrons flow from the metal with the higher affinity to the metal with lower affinity and electrical current is generated. protons flow from the metal with the higher affinity to the metal with lower affinity and electrical current is generated.
