A 24-kg wagon accelerates on a horizontal surface at 0.7 m/s2 when pulled by a rope exerting a 120-N force on the wagon at an angle of 25o above the horizontal. Determine the magnitude of the effective friction force exerted on the wagon Express your answer to two significant figures and include the appropriate units. Determine the effective coefficient of friction associated with this force. Express your answer to two significant figures.
