Final answer:
The question does not specify the top speed limit in New Jersey, instead focuses on unit conversions. A speed limit of 100 km/h is approximately 62.14 miles per hour. For 80 km/h, the conversion to meters per second would yield 22.22 m/s.
Step-by-step explanation:
The set top speed limit for certain state highways and all interstates in New Jersey is not specified in the question. However, in physics problems, common highway speed limits are often used as examples for conversions between units of speed. One such example provided is the conversion of a speed limit of approximately 100 km/h, which is a typical speed limit on some highways. To convert this into miles per hour, you use the conversion factor where 1.0 mile is about 1.609 kilometers:
(100 km/h) / (1.609 km/mile) = approximately 62.14 miles per hour
This indicates that 100 km/h is roughly equivalent to 62 miles per hour. Similarly, to find out how many meters per second a speed of 80 km/h is equivalent to, the conversion would be:
(80 km/h) * (1000 m/km) / (3600 s/h) = 22.22 meters per second
In the United States, typical interstate highway speed limits are around 60-70 miles per hour, though this can vary depending on the state laws and road conditions.
