A vertical chemical reactor undergone a maintenance in which its internals were subjected inspection from bottom to top before catalyst loading. A site engineer (63.00 kg) was tasked to do the inspection and he stopped from time to time at each portion to inspect. A safety officer monitored the engineer’s position while watching from the top and reported his position (Refer to the photo attached. CORRECTION for data table at t=70.00 min, position=725.0 cm): Solve for: (a) Power he exerted at t = 50.00 min (b) Power he exerted at t = 65.00 min (c) Total Work he exerted throughout the inspection (d) Average Power throughout the inspection
