Distance traveled by the policeman= ut+1/2at^2
u= initial velocity = 0
a= 3
t= 12
so D = 1/2 X 3 X 144 = 216
Now Final velocity at which he is chasing constantly = 12 X 3 =36m/s
Distance traveled by the robbers = 12 X 20 = 240
Distance between both = 240 - 216 = 24m
using relative speed,
speed= 36-20 = 16m/s
Time = 24/16 = 1.5
Distance traveled by policeman in this time = 36 X 1.5 = 54m
Total distance = 216 + 54 = 270m
u= initial velocity = 0
a= 3
t= 12
so D = 1/2 X 3 X 144 = 216

Answer:
force is a push or pull acting upon an object as a result of its interaction with another object. ... Previously in this lesson, a variety of force types were placed into two broad category headings on the basis of whether the force resulted from the contact or non-contact of the two interacting objects.
hii... how are you???
good evining
