Homework Statement
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).
Homework Equations
kinematics equations
and the graph is used
The Attempt at a Solution
I drew the graph which looks like a trapezoid... but I don't know what to do after that.
