Is it true that speed kills the MPG?

Speed Kills MPG Unfortunately, it’s true. Your car’s gas mileage decreases once it gets past its optimal speed. For most cars, this is around 55-60 mph. This means that every time you go over this speed, you’re essentially wasting gas and money – and creating unnecessary greenhouse gases.

Now I can use that for the maximum acceleration during a collision. Here are the values for 70 mph (31 m/s) and 85 mph (38 m/s) Ok, I am happy. First, this is the acceleration at the maximum compression for a spring. However, my special spring doesn’t bounce back.

How to calculate the acceleration of 60 mph?

The answer is (60 mph – 0 mph) / 8s = (26.8224 m/s – 0 m/s) / 8s = 3.3528 m/s 2 (meters per second squared) average acceleration. That would be 27,000 miles per hour squared.
