1. The problem statement, all variables and given/known data A car starts from rest and accelerates uniformly for 200m. It moves at constant speed for 160m and then decelerates to rest in 50m. The whole trip takes 33s. How long did it move at constant speed? (hint: draw the v versus t graph). 2. Relevant equations kinematics equations and the graph is used 3. The attempt at a solution I drew the graph which looks like a trapezoid... but I don't know what to do after that.
