=11.25m

Explanation:

From given graph we see that the two vehicles retarded uniformly to zero velocity.

The area under each v-t graph is the measure of the distance traversed . So total area is the total distance traversed after the application brakes at t=0.

Total distance =(1/2xx10xx2.5+1/2xx15xx3.5)m=(12.5+26.25m)

=38.75m

At =0 the distance between the vehicles is 15-(-35)m=50m

So when the two vehicles will come to rest the distance of separation between them will be =(50-38.750m=11.25m
