Hello, I need some help with some questions b/c I have been out sick and I am still sick and have missed all this info and my teacher emailed me my homework, so can you please help me I would really appreciate it, I have skipped most of the problems, I just need help with these!

1.What are the units of a velocity vs time graph? " What does it mean units"

2.On the graph below draw the acceleration vs time graph for the object moving at a constant speed. " Would it be a graph just with a horizontal line?"

3. There is a graph of DISPLACEMENT vs time for an object with constant acceleration. The line on the graph is curving upward. What does this d v t graph tell us about the speed?

4. Find the instantaneous velocities at each second using the graph below the tangent lines are draw in

5. Use the instantaneous velocities from number 4 draw a v v t graph remembering to label your axes. Calculate the slope of the line. What does this slope represent?

6. Draw an acceleration vs time graph, remembering to label your axes

7. What does the slope of the d v t graph tell you?

8. What does the slope of the v v t graph tell you?

9. Find the area underneath the v v t curve below. What is the length of the base? What is the height? Calculate the area?

10. What do the units indicate the area under a v v t graph show us?

11. What do you think the area under the a v t graph graph represents?

Thanks for all your help, I really really appreciate this!
