## Homework Statement

I need to use the following data table to:

1. make a position-time graph

2. draw tangents (it isn't specified how many, but a previous practice question only drew 3 out of a possible 5)

3. create a time-velocity table.

0 --- 0

0.25 --- 0.29

0.50 --- 1.15

0.75 --- 2.59

1.00 --- 4.60

1.25 --- 7.19

1.50 --- 10.35

## Homework Equations

vinst = d/t

## The Attempt at a Solution

The position-time graph is attached. I think that's right, but what I'm really having trouble with is drawing the tangent lines and calculating the instantaneous velocity. I feel like I didn't draw the tangents right but I'm not sure how to do it differently.

Here's my calculations:

0.50: 7 / 1.75-0.25 = 3.7

1.00: 10 / 1.65-0.50 = 5.5

1.50: 10 / 1.50-0.75 = 6.2
