Please please answer everything super fast **Designing Freeway Ramps: A Practical Guide**When designing a freeway on-ramp, it is crucial to ensure cars can accelerate and merge safely with traffic traveling at speeds of 70 mph. Similarly, for off-ramps, cars must be capable of coming to a complete stop from 35 mph over the length of the ramp. Traffic engineers have provided the following data to assist in this task:- **Powerful Cars:** Can accelerate from rest to 50 mph in 5.2 seconds.- **Less Powerful Cars:** Require twice as much time to reach the same speed.- **Stopping Distances:** - With good tire treads, a car will take 8.4 seconds to stop from 35 mph. - With bald tires, the stopping time increases to 16.6 seconds.**Part A: On-Ramp Design**To accommodate all vehicles safely, the following question is posed:"What should be the minimum length (in meters) of on-ramps?"Please express your answer using two significant figures.\( L_{on} = \) ______ m**Part B: Off-Ramp Design**To ensure safety for all vehicles, determine:"What should be the minimum length (in meters) of off-ramps?"Provide your answer with two significant figures.\( L_{off} = \) ______ mThis guide is an essential resource for ensuring the safe and efficient design of freeway entrance and exit ramps.

The merging speed is 70 mph = 1 mph= 0.44704 m/sAs per the…

In designing a freeway on-ramp, you must make it long enough for cars to be able to accelerate and merge safely with traffic traveling at speeds of 70 mph. For an off-ramp, the cars must be able to come to a stop from 35 mph over the length of the ramp. Your traffic engineers provide the following data: Powerful cars can accelerate from rest to 50 mph in 5.2 s, while less powerful cars take twice as long to do this. When slowing down from 35 mph, a car with good tire treads will take 8.4 s to stop, whereas one with bald tires takes 16.6 S.
