Tara, driving at 30 m/s, enters a one-lane tunnel. She then observes Sean's slow moving van 155m ahead traveling at 5 m.s. Tara applies her brakes but can accelerate at only -2.00m/s/s because the road is wet. will there be a collision? if so, determine how far in the tunnel it occurs and at when it occurs. If not, determine the final distance between Tara and Sean.
