Speedy Sue, driving at 34.0m/s, enters a one-lane tunnel. she then observes a slow moving van 170m ahead traveling at 5.50m/s. sue applies her brakes but can accelerate only at -1.30m/s2 because the road is wet. (a) will there be a collision? (b) if yes, determine how fat into the tunnel and at what time the collision occurs. if no, determine the distance of closest approach between Sue's car and the van. (if no, enter "0" for the time)
