    Finding a collision time....

    1. The problem statement, all variables and given/known data
    Sue, driving at 33 m/s enter a one lane tunnel. She then observes a slow moving van 175 m ahead traveling with velocity 5.40 m/s. Sue applies here brakes but can accelerate at only -2.00m/s^2.


    2. Relevant equations
    Determine how far into the tunnel and at what time the collision occurs.

    3. The attempt at a solution

    Hello,

    FYI, it's forum policy that you show the relevant equations and, more importantly, show your attempt at solving the problem, before you can get help with it.
