2. Margareth, driving at 40.0 m/s, enters a one-lane tunnel. She then observes a
slow-moving van 205 m ahead traveling at 6.00 m/s. Margareth applies her brakes
but can accelerate only at -2.50 m/s? because the road is wet. Will there be a
collision? State how you decide. If yes, determine how far into the tunnel and at
what time the collision occurs. If no, determine the distance of closest approach
between Margareth's car and the van.
