Una familia viaja de vacaciones al sur de Chile, recorriendo en su automóvil una distancia de 500 [km] en 5 [h], tal como muestra la figura. Si la distancia en línea recta entre el punto de inicio y el punto final del viaje es de 350 [km], y se sabe que la familia se detuvo en distintas partes del camino, es correcto afirmar que: * 1la rapidez media con la que se movió el auto durante el viaje fue de 70 [km/h].
2la magnitud del desplazamiento fue de 500 [km].
3la magnitud de la velocidad media con la que viajó la familia fue de 100 [km/h].
4la rapidez media del auto coincidió con la magnitud de la velocidad media.
5 la rapidez media con la que se movió el auto durante el viaje fue de 100 [km/h].

This problem has been solved! see the answera non-uniform fire escape ladder is 6.0m long whenextended to the icy alley below. it is held at the top by africtionless pivot, and there is neglibible frictional force fromthe icy surface at the bottom. the ladder weighs 250n, and it'scenter of gravity is 2.0m along the ladder from the bottom. amother and child of total weight 750n are on the ladder 1.5m fromthe pivot. the ladder makes an angle θ with the horizontal.find the magnitude and direction ofa) the force exerted by the icy alley on the ladderb) the force exerted by the ladder on the pivotc) do your answers in part a and b depend on the angle?
