Determine el valor de la aceleración en el sistema representado en la figura, teniendo en cuenta que el cuerpo 1 es de 5kg con coeficiente de rozamiento de 0,2 y el cuerpo 2 es de 8kg. El ángulo de inclinación es de 60 grados con respecto a la horizontal .Nota :tome el sentido a favor de las manecillas del reloj .

Tafari worked one summer on a ship that set weather buoys in the ocean. he watched how one of the buoys moved in the water. describe which parts of the wave would cause the buoy to bob up and down. which wave property determined how fast the buoys bobbed in the water? he observed that when the wind blew harder, the ocean waves were larger, and the buoys moved away from the ship. what effect, if any, did the waves have on how far the buoys moved? explain your answer.

Your target variable is δf, the magnitude of the difference in frequency between the waves emitted from the sonar device and the waves received by the device after reflecting off the whale. write an expression for δf in terms of the relevant frequencies using the subscript notation introduced above.
