See the example Capstone graph from the Lab Manual (Figure 3, a velocity vs. time curve). What region of this graph represents the time when the cart is moving down the incline?

1) From A to C

2) From B to C

3) From A to B

I am not certain how to answer this. Please help as soon as possible? Thank you?

2nd Question:

See the example Capstone graph from the Lab Manual (Figure 3, a velocity vs. time curve). Once you have created a graph like this, what will you do with it?

1) Make a quadratic fit to the data (From A to C) to find the acceleration.

2) Find the time at which the curve crosses the V=0 x-axis(point B).

3) Make a linear fit to the data(From A to C) to find the acceleration.

4) Make two linear fits to the data (one from A to B, and the other from B to C), to find two accelerations.

5) Make two quadratic fits to the data(one from A to B, and the other from B to C), to find two accelerations.

I'm stuck between 3 and 4 answers. one linear or two linears?? Please help soon as possible. Thank you.
