A 7.76 kg crate slides on a horizontal surface. The coefficient of kinetic friction between the surface and the crate is 0.34. There is an external force pushing the crate to the right, directed 32.1o below the horizontal. If the crate slides with a constant velocity, 7.1 m/s, what is the magnitude of the external force acting on the crate? Report your answer in SI units with three significant figures.
