1. The problem statement, all variables and given/known data See the attachment please. 3. The attempt at a solution I know the v1 x delta (t) is for the rectangle, I dont see how the second part works? I dont understand why the t^2 and how a replaces the area formula i have written. Thanks for your help, its my first day of class today, and its been a while since i was last in a physics / math class. EDIT: I added a formula sheet we were given, sorry i just dont see the relationship right now..
