mAJOR help :/
I did this problem, I know I did and I lost my work.

Speedy sue, driving at 30.0 m/s, enters a one lane tunnel. She then observes a slow moving van 155m ahead traveling at 5.00 m/s. Sue applies her brakes but can accelerate only at -2.00 m/s^2 because the road is wet. will there be a collision? state how you decided. if yes, determine how far into the tunnel and at what time the collision will occur. If no, determine the distance of closest approach between sues car and the van
