Un trineo con masa de 8.00Kg se mueve en línea recta sobre una superficie horizontal sin fricción. En cierto punto, su rapidez es de 4.00 m/s; mas adelante, su rapidez es de 6.00 m/s. Utilice la definición de trabajo y energía cinética para determinar la fuerza que actúa sobre el trineo, suponiendo que tal fuerza es constante y actúa en la dirección del movimiento del trineo.
