una caja de 50kg que se desliza sobre una superficie horizontal es jalada por un hombre con una fuerza de 160 N a 30 grados con la horizontal. Calcula la aceleracion del objeto si el coeficiente de friccion es de 0.15

An experiment was performed on a 2-kg block. forces of 5, 10 and 15 newtons respectively were applied to the block for 5 seconds. describe the difference in acceleration between the three trials. a) the final accelerations will all be the same. b) the final acceleration will triple between the first and third trial. c) the final acceleration will be cut by 1/3 from the first to third trial. d) the final acceleration will increase nine time between the first and third trial.
