A blue car of length 4.52 m is moving north on a roadway (hat intersects another perpendicular roadway (Fig. P2.81, page 58). The width of the intersection from near edge to far edge is 28.0 m. The blue car has a constant acceleration of magnitude 2.10 m/s2 directed south. The time interval required for the nose of the blue car to move from the near (south) edge of the intersection to the north edge of the intersection is 3.10 s. (a) How far is the nose of the blue car from the south edge of the intersection when it stops? (b) For what time interval is any part of the blue car within the boundaries of the intersection? (c) A red car is at rest on the perpendicular intersecting roadway. As the nose of the blue car enters the intersection, the red car starts from rest and accelerates east at 5.60 m/s2. What is the minimum distance from the near (west) edge of the intersection at which the nose of the red car can begin its motion if it is to enter the intersection alter the blue car has entirely left the intersection? (d) II the red car begins its motion at the position given by the answer to pan (c), with what speed does it enter the intersection?

Two cars are moving towards an intersection. One car is 150 meters north of the intersection and moving towards the intersection at 20 m/s, while the other is 180 meters west of the intersection and moving towards the intersection at 16 m/s. How rapidly are the cars approaching each other 4 seconds later?
Christopher watches a stick float downstream in a river and notices that it moves 15 m [El in a time of 2.5 x 10' s. His friend, John, is starting on the south side of the river and is going to swim across. In still water, John knows that he can swim with a speed of 1.2 m/s, relative to the water. a) What is John's velocity relative to the shore? b) If the river is 1.5 km wide, how long will it take John to cross the river? c) How far downstream will be land?
