Question
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 At a later moment, the forces are simultaneously withdrawn.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, F
the average power delivered to the block by force ₁ is P₁.
The average power P₂ delivered to the block by force F₂ is:
