First of all the velocity of car A is 20/5=4m/s
now if both car moves side by side at t=6sec that means they have same velocity at t=6sec
therefore for Va=Ua+f*6
or Va=4+6f
and for car B
Vb=Ub-f*6
or Vb=10-6f [for B accleration is negative
now Va=Vb
therefore
or 4+6f= 10-6f
or f=.5m/s^2
b) for the value of same f Car B's final velocity=10-6*.5= 7m/s
then for negative accleration the velocity will be zero after coving s distance
therefore using V^2-U^2=2fs we get 0-7^2=2*.5*s
or s=4.9m
therefore the cars will be side by side for two times once when the velocity is 7m/s and secondly when B comes to rest at 4.9m

Two cars A and B approach each other in two adjacent lanes of
a linear track in opposite directions, as shown in the figure. at t
= 0s, A and B are at D = 21m away, the car A departs from rest and
moves with a constant acceleration of aA = 2m / s ^ 2 and auto B
moves with constant velocity of Vb = 4m / s.
a) find the position based on time for both cars,...
In the figure here, a red car and a green car move toward each
other in adjacent lanes and parallel to an x axis. At time t = 0,
the red car is at xr = 0 and the green car is at xg = 219 m. If the
red car has a constant velocity of 22.0 km/h, the cars pass each
other at x = 43.3 m. On the other hand, if the red car has a
constant velocity...
