Concept Development Practice Page 5 3 - The block is at rest on a horizontal surface. How much work (energy) is needed to lift an object that weighs 200 n to a height of 4 m? There is (friction) (no friction). The normal support force n is equal and opposite to weight w. When two vectors a and b are at an angle to each other, they add to produce the resultant c by the parallelogram rule. Neglect air drag and assume g = 10 m/s2. What is the power output of an.
