the v-axis scale is set by vs = 7.00 m/s. (a) What is the coordinate of the particle at t = 5.0 s? (b) What is the velocity of the particle at t = 5.0 s? (c) What is the acceleration of the particle at t = 5.0 s? (d) What is the average velocity of the particle between t = 1.0 s and t = 5.0 s? (e) What is the average acceleration of the particle between t = 1.0 s and t = 5.0 s?

## Homework Equations

V

_{f}= V

_{i}+at

V

_{avg}= (V

_{f}+V

_{i})/2

a

_{avg}= change in v/change in time

## The Attempt at a Solution

I think all my answers are wrong!

a) (2,5) --> Looking at the graph

b) t =5s, v=2 m/s

c) V

_{f}= V

_{i}+at

(4-2)/1 = a

a = 2 m/s

d) V

_{avg}= (V

_{f}+V

_{i})/2

(2=2)/2

= 2 m/s

e) a

_{avg}= change in v/change in time

=0 m/s
