Acommon form of unwanted energy is an energy transformation is

The average time that it takes for the car to travel the first 0.25m is s. the average time to travel just between 0.25 m and 0.50 m is s. given the time taken to travel the second 0.25 m section, the velocity would be m/s.

If a 250-g mass is hung on two identical springs, hung side by side , and both support the 250-g mass, how much will each spring stretch?

Plz suppose you increase your walking speed from 6 m/s to 13 m/s in a peroid of 3 s. what is your acceleration you in advance.
