Calcular la aceleración (en m/s2) que se aplica para que un móvil que se desplaza en línea recta a 90 km/h reduzca su velocidad a 50.0 km/h en 25 segundos.
Answers: 1
![90[\frac{km}{h} ]*[\frac{1h}{3600s} ]*[\frac{1000m}{km} ]=25[m/s]\\50[\frac{km}{h} ]*[\frac{1h}{3600s} ]*[\frac{1000m}{km} ]=13.88[m/s]](/tpl/images/0930/3078/d3084.png)
![13.88=25-a*25\\25-13.88 = 25*a\\25*a=11.11\\a=0.44[m/s^{2} ]](/tpl/images/0930/3078/24b25.png)
