10 the power of a motor is 40 kW, at what speed can the motor raise a load of 20,000 N ans 2 ms 1

If the power of a motor is 40 KW, at what speed can it raise a load of 20,000 N?

Power = 40KWForce = 20,000NPower = force × velocity

Velocity =`"Power"/"Force"=(40"KW")/(20,000)=(40,000)/(20,000)=` 2 m/s.
