Acar accelerates from 13-m/s to 24.1-m/s in 5.4-s. what was its acceleration in m/s2?

First you must find the change in velocity: 24.1m/s - 13m/m = 11.1m/s
Then you divide the change in velocity by the time it took to change to find the acceleration.
11.1m/s÷5.4s =2.056 m/s^2

1) when you rub your hands together quickly, the kinetic energy is converted to mechanical energy.2) thermal energy from the sun travels to earth as infrared waves.3) energy is transferred through the matter of space by electromagnetic waves. 4) when a match is burned, chemical potential energy is converted to thermal and radiant energy. 5) seismicwaves are caused by back and forth movement , or vibration, of an object. 6) mechanicalenergy in an engine changes thermal energy into kinetic energy to make a car move.
