Sobre un plano inclinado que forma 37° con la horizontal, se encuentra un bloque A, de masa 6 , unido por medio de una cuerda a otro bloque B, de masa 3 que cuelga de la cuerda, la cual pasa por una polea situada en la parte inferior del plano. Si el coeficiente de rozamiento entre el bloque y el plano es = 0.4, calcular la aceleración del sistema y la tensión del hilo.

i will answer your question if you answer mine

answer: the metamorphic rocks are formed when they are exposed to high pressure and high temperatures. this happens when one of the earth's plates comes in contact with the other plate by traveling in opposite directions, straight into each other or slipping under one another. the friction that is caused by this activity results in   melting of rocks and when it cools they are known as metamorphic rocks. this process needs a controlled amount of pressure and temperature otherwise it may turn into magma.

false.

explanation:

this statement is false. after falling for 5 seconds, its speed will not be 100 m/s.
