Answer:
we have to measure the distance between two moving cars (any vehicle) moving with variable speed
while the full apparatus is in the car running behind no part of device is placed on car in front
car in front can be made of any material (reflector or non reflector) and can be of any shape
both cars are in same plane
assuming relative speed to be 1-16 meter per sec
info is required in real time and output should voltage or current and proportional to distance
distance must be measured continously(as it is changing with changing speed)
max distance between them can be 8-10 meter
