- Homework Statement
- From the graph evaluate-

1) average velocity for first 6sec

2) average speed for first 6sec

3) average acceleration from1 to 4sec

4)instantaneous a at 3rd sec

5) plot a-t and x-t graph assuming x=0,t=0

- Relevant Equations
- ##{v_{avg}}=displacement/time##

##average speed= distance/time##

Etc…

3) and 4) is easy. Average and instantaneous acceleration is same from 1 to 4 sec since it’s constant acceleration.

1) and 2) I am unable to get the correct area under the curve.

##s = \frac 12*(-5)*1 + \frac12*10*2 + 10*1 + \frac12*10*1##

Same I guess will be distance.

5) what is the graph of x-t

I have attached the graph below.
