1. The problem statement, all variables and given/known data Car P is 1km from finish line with a speed of 35ms-1 and a uniform acceleration of 2/5ms-2 Car Y is 1.2km from finish line going at 44ms-1 and a uniform accelr of 1/2ms-1 show that Y passes p 220m before the finish line. 2. Relevant equations v2=u2+2as s=vt-1/2at^2 3. The attempt at a solution so the acceleration when they are both in the same position is 0. thus i can use s=vt-1/2at^2 for both and cancel them out. so it would be 220=(44)t-(1/2)(1/2)t^2 for Y and for P it would be 220=(35)t-1/2(2/5)t^2. but then i end up with 0=9t-(1/20)t^2. then what???? after that I'm lost.
