A load of 20000N is being raised by a motor having a power of 40 kW. What is the speed with which the load gets raised
Dear Student, 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. Regards
