Ayuden Plis Un camión parte del reposo hacia el norte y alcanza una velocidad cuya magnitud es
de 40 km/h en 5 segundos. Calcula cual fue la magnitud de su aceleración en m/s2

Two steel balls, each of mass m, are welded to a light rod of length l and negligible mass and are initially at rest on a smooth horizontal surface. a horizontal force of magnitude f is suddenly applied to the rod as shown. determine (a) the instantaneous acceleration a of the mass center g and (b) the corresponding rate at which the angular velocity of the assembly about g is changing with time.
