A crane (il) lifts a plate of blocks at a construction site in Khor Bamba ( ) in 3 stages using a motor. Each stage moves the plate up by 14m as follows: First the plate is accelerated to 9.1 m/s, then lifted at a constant speed of 9.1 m/s, and finally the plate is decelerated to zero speed. [Recommended time : 4-5 minutes] How much work is done on the 4.4 Ton plate by the crane? O a. 1993.2 kJ O b. 1811.0 kJ O c. 2175.4 kJ O d. 785.9 kJ
