Question: How much work does it take to slide a crate 21 m along a loading dock by pulling on it with a 160-N force

How much work does it take to slide a crate 21 m along a loading dock by pulling on it with a 160-N force at an angle of 27 from the horizontal? The work done is (Round to the nearest whole number as needed.) The vector v = ai + bj is perpendicular to the line ax + by = c. Use this fact to find an equation of the line through P perpendicular to v. Then draw a sketch of the line including v as a vector starting at the origin. P(-2, 7)v=-2i+j The equation of the line is (Type an equation.)
