La rapidez de una particula que se mueve a lo largo del eje x varia con el tiempo de acuerdo con la expreion v=(15-3t2) m/s donde t esta en segundo. Calcula la aceleracion media en el imtervalo de t=0 s y t =2s

the motion of a pendulum is a classic example of mechanical energy conservation. a pendulum consists of a mass (known as a bob ) attached by a string to a pivot point. as the pendulum moves it sweeps out a circular arc, moving back and forth in a periodic fashion.

truck y has a greater velocity than truck x.
