A block is at rest on a horizontal frictionless table. At t = 0, two perpendicular horizontal forces of magnitudes F₁-F and F₂-kF are applied to the block as shown. At a later moment, the forces are simultaneously withdrawn. By that time, the average power delivered to the block by force F₁ is P₁. F The average power P₂ delivered to the block by force F₂ is: kP₁ O O X k²P₁ P P₁ √² + kP₁ √k² + k² P₁ √k² +1 k² P₁ k² +1 Top View >kF Save
