Problem 2 A project by some to monitor the traffic safety at a busy intersection. They measure (with a precision stopwatch) that exactly three seconds after car B passes through the intersection traveling south at vg = 55 mph, minivan A passes through at va = 70 mph on the road that runs at an angle 0 = 60° east of north. The speed of each automobile is Civil Engineering students requires them constant. VB Determine (a) the relative velocity (in mph) of B with respect to A, draw the vector triangles as part of your answer (b) the change in position (in fi) of B with respect to A during a 10-s interval, (c) the distance (in ft) between the two automobiles 3 s after A has passed through the intersection.

One vehicle is following another on a two-lane, two-way highway at night according to the safe-driving “rule-of-thumb” of one car length spacing for each 10 mph of speed. Both of you traveling at 70 mph when the lead vehicle crashes into an unlighted disable vehicle. Assuming that one car length is 20 feet, f=0.28 and PIEV time is 1.5 for you, will you hit the lead vehicle? If so at what speed will you be going?
