1.	40V A constant force vecF is acting on a body of mass m makes it move with constant velocity vecv as shown in the M figure. The power P exerted is
Answer» `F cos theta V` `(F cos theta)/(MG)` `(F mg cos theta)/(v)` `(mg sin theta)/F` Solution : POWER = (COMPONENT of FORCE in the direction of velocity) `\|vecv\|` `= F cos theta v`.
