Speedy Sue, driving at 32.0 m/s , enters a one-lane tunnel. She then observes a slow-moving van 175 m ahead traveling with velocity 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?
A) Yes or No
B) If yes, determine how far 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 and enter zero for the time.
distance
______m
time
______s
Notice that not distance but here position has been determined and has been equated.
