mass of s of 150kg If the upward speed of the hoist increases uniformly from to 1.5m/s to 21m/s in 1.9s, determine the averag generated by the motor M during this time. The motor operates with an efficiency of =0.8 Express your answer to three significant figures and include the appropriate units. The material hoist and the load have a total mass of 900kg and the counterweight C has a mass of 150kg. (Figure 1) If the upward speed of the hoist increases uniformly from to 1.5m/s to 2.1m/s in 1.9s, determine the aver generated by the motor M during this time. The motor operates with an efficiency of =0.8. Express your answer to three significant figures and include the appropriate units. 1 of 1
