An elevator is designed to lift a load of 1000 kg with uniform velocity of 2m/s . Power of the elevator will be?

Since the load is lifted with constant speed , Force F = mg = 1000 × 9.8 = 980 N
 
where m is mass of load and g is acceleration due to gravity.
 
Power = force × speed = 980 × 2 = 1960 W

Hi, my name is Aprameya i had a doubt we know K.E.(Kinetic Energy) = (1/2)mv^2 the v over here is velocity but at what time. Velocity will be different at differnt points of time i mean at 1second it might be something and and at another second it might be something else. so while calculating which velocity do we use
