A 150-newton force, applied to a wooden crate at an angle of 30° above the horizontal, causes the crate to travel at constant velocity across a horizontal wooden floor. 1. Calculate the magnitude of the normal force exerted by the floor on the crate. [Show all work, including the equation and substitution with units.]=
