# College Physics 2.66 – Solving for velocity and acceleration from position graph

## Solution:

### Part A

The velocity of the particle is the slope of the position vs time graph. Since the position graph is compose of straight lines, we can say that the velocity is constant for several time ranges.

Based from the data in the table, we can draw the velocity diagram

### Part B

Since the velocity is constant between 0 seconds and 2 seconds, we say that the acceleration is 0.

### Part C

Since there is a sudden change in velocity at exactly 2 seconds in a very short amount of time, we say that the acceleration is undefined in this case.
