Heya......!!!!

____________________________

This question can be easily solved by applying the formulae :-

=> P = F v

here : P = Power. F = Force. v =Velocity .

Given in the question :

• Power = 40 kW = > 40 × 1000 = 40000 W

• Force = 20000 N

putting values in formulae :

=> 40000 = 20000 × v

=> v = 40000 / 20000

=> Velocity = 2 m/s

Hey

Power = 40 kW = 40000 W , Force = 20,000 N 
As, Power= force x velocity 
       ∴  40,000 = 20,000 x v
        ⇒ v = 40,000/ 20,000
        ⇒ v = 2 m/s
Therefore at the speed of 2 m/s speed can raise a loud of 20,000 N. 

Hope it helps to you.
