1. The problem statement, all variables and given/known data 2. Relevant equations 3. The attempt at a solution the displacement should be the area under the line , it was traveling backwards for 3 seconds, then it would take an additional 3 seconds to get back to the starting position. From there, the wheel rotates forward for 4 more seconds for a total of 10 seconds. So do I need to find the area of the entire triangle (from seconds 0 to 10) then subtract the smaller triangle (from seconds 0 to 6) to be left with only the area of (seconds 6 to 10)?
