Una bola de nieve rueda del techo de un granero con una inclinación hacia debajo de 40,0 grados. El borde del techo está a 14,0
m del suelo y la bola tiene una rapidez de 7,00 m/s al salir del
techo. Ignore la resistencia del aire.

Analice si la rapidez final con la que impacta la bola supera el
doble de la rapidez inicial con la que sale del techo.

Aperson gives a shopping cart an initial push along a horizontal floor to get it moving, and then lets go. the cart travels forward along the floor, gradually slowing as it moves. consider the horizontal force(s) on the cart while it is moving forward and slowing. which of the following statements is correct? (a) both a forward and a backward force are acting on the cart, but the forward force is larger. (b) only a forward force is acting which diminishes with time. (c) both a forward and a backward force are acting on the cart, but the backward force is larger. (d) only a backward force is acting, no forward force.
