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.

answer would be letter choice (a),   a ball resting on a shelf. would be another example of potential energy   >   stored energy > not moving.

a ball spinning on a finger   >   kinetic energy > moving energy

a ball rolling on the ground   >   kinetic energy   > moving energy

a   ball flying through the air   > kinetic energy   >   moving energy

hope that                                         : )

the best answer for these questions would be:

1.            c. is smaller

2.            d) concrete operational

3.            b) interaction with the environment – the children interact with their environment can them learn more.

4.            a) parents who reason openly with children can limit a child’s cognitive ability.
