Step 1

A body moves  on a coordinate  line such that  it has a  position  on the interval , with in  meters and t in seconds.

1. Find the body’s displacement and average velocity for the given time interval
2. Find the body’s speed and acceleration at the end point of the interval
3. When, if ever, during the interval does the body change direction?
Step 2

To find the displacement we need to find the s(b)- s(a) in the given interval

Step 3

The displacement for th... help_outlineImage Transcriptionclose0st4 is s(4)-s(0) Displacement=[(4)-5(4)+4]-[(0)2-5(0)+4] -[16-20+4]- 16-20+4-4 4m The average velocity is the displacement divided by the time elapsed 4 4 0 m/sec fullscreen
