- A 284N crate resting on a plane inclined 37-degrees with the horizontal requires a 23.9N force to bring it down to 6.4m from its initial position. The force is applied 55-degrees with respect to the horizontal. Neglecting friction between the crate and plane, determine the time (in seconds) that the crate had travelled a distance of 6.4m. Answer in two decimal places. Numerical values only. Don't indicate units here, just on the submitted solution.A 247N crate resting on a plane inclined 25-degrees with the horizontal requires a 28N force to bring it down to 7.1m from its initial position.
