Problem P. 4095. (October 2008)
P. 4095. The traffic in some part of a three-lane motorway is restricted to only one lane. In this part the cars move uniformly at a speed of 54 km/h and 11-m long gaps are formed between them.
a) What is the speed of the cars before the one-lane part, if the gap between them is 2 m?
b) What will the length of the gaps between the cars be after the one-lane part if the cars speed up to a velocity of 126 km/h?
Let us consider the length of each car 4 m.
