A speeder is driving his car at a constant speed of 35.0 m/s on a wet one-lane highway. He then enters a tunnel and observes a slow driving truck 135 m ahead traveling at 4.00 m's. He applies his brakes and accelerates at -2.00 m/s. At what time do they collide? How far into the tunnel do they collide? a. b. e hat is the mini lin Bbtne beh uchsder wohyeato the brakes to prevent from colliding with the truck?
Speedy Sue, driving at 35.0 m/s, enters a one-lane tunnel. She then observes a slow-moving van 160 m ahead traveling at 5.50 m/s. Sue applies her brakes but can accelerate only at −1.90 m/s2 because the road is wet. Will there be a collision? 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. (If no, enter "0" for the time.)
