Un objeto de 8kg se desliza por un plano inclinado, que forma un ángulo de 30º con la horizontal. Si el objeto inicialmente se encontraba en reposo y a una altura de 12m. Aplica el principio de conservación de la energía y determina la velocidad con que el objeto llega al final del plano, si no hay rozamiento.

Talia took the bus from her home to the bank and then walked back to her home along the same route. the bus traveled at an average speed of 40 km/h and she walked at an average speed of 5 km/h. to determine the time, x, that it took talia to walk home, she used the equation 40(0.9 – x) = 5x. the time of trip 2 is hours. the distance of trip 1 is km.
