Homework Help: Grade 12 Physics

Posted by Haley on Wednesday, September 12, 2007 at 4:36pm.

A young woman named Sassy Sue purchases a sports utility vehicle that can accelerate at the rate of
4.88m/s^2. She decides to test the car by dragging with another speedster, McSpeedy. Both start from rest, but experienced McSpeedy leaves 1.0s before Sue. If McSpeedy moves with a constant acceleration of 3.66m/s^2 & Sue maintains an acceleration of
4.88m/s^2, find the distance she travels before catching him.

So far I have displacement of Sue is 2.44deltat^2
McSpeedy's v2 before Sue starts: 3.66m/s
McSpeedy's displacement: 1.83delta t^2

I am missing parts and can't figure out what

Any ideas?
