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
